The question asks about the state of matter responsible for the glow of the Sun and stars. This requires knowledge of the extreme conditions present in these celestial bodies and the resulting state of matter.
B) Plasma — The Sun and stars are primarily composed of plasma, a superheated, ionized gas where electrons are separated from atomic nuclei. This state of matter is responsible for the nuclear fusion reactions and the emission of light and heat that make these celestial bodies glow.

The problem presents a series of alphabet pairs. To find the missing group, we need to identify the pattern in the positions of the first and second letters of each pair in the English alphabet.
The first letters in the series are V, N, (?), D, B.
Let's find the difference in their positions:
The differences are decreasing: 8, (?), 2. This suggests a pattern of decreasing subtractions. If the pattern is \( -8, -6, -4, -2 \), then the missing first letter should be N - 6.
Let's check if H (8) - 4 = D (4). Yes, \(8 - 4 = 4\). This confirms the pattern for the first letters: \( -8, -6, -4, -2 \).
The second letters in the series are A, D, (?), P, Y.
Let's find the difference in their positions:
The differences are increasing: 3, (?), 9. This suggests a pattern of increasing additions. If the pattern is \( +3, +5, +7, +9 \), then the missing second letter should be D + 5.
Let's check if I (9) + 7 = P (16). Yes, \(9 + 7 = 16\). This confirms the pattern for the second letters: \( +3, +5, +7, +9 \).
The missing first letter is H, and the missing second letter is I.
Therefore, the missing group of alphabets is HI.
Correct Option: C) HI
The question asks to identify the Indian Union Territory to which Amindivi and Minicoy islands belong. This requires knowledge of the geographical divisions and administrative units of India, specifically regarding its island territories.
Correct Option: A) Lakshadweep is the Union Territory that includes the Amindivi and Minicoy island groups. These, along with the Laccadive islands, form the Lakshadweep archipelago in the Arabian Sea.
This is a circular seating arrangement problem. We need to deduce the positions of eight friends (A, B, C, D, E, F, G, H) sitting around a circular table, all facing the center, based on the given clues. We will place individuals one by one, using direct and indirect information, and eliminate possibilities until the arrangement is complete.
Clue 1: A is second to the right of G who is third to the right of B.
Let's place B first. Since everyone is facing the center, "right" is clockwise.
Combining these, we get the sequence: B _ _ G _ A. This means there are two people between B and G, and one person between G and A. Let's denote the positions:
Position 1: B
Position 2: ?
Position 3: ?
Position 4: G
Position 5: ?
Position 6: A
Clue 2: D is second to the left of F who sits between G and A.
Updated sequence: B _ _ G F A
If F is at Position 5, then Position 4 is G, Position 6 is A. Second to the left of F would be Position 3 (one person between D and F).
Updated sequence: B _ D G F A
Combining and filling remaining spots:
So far, we have: B _ D G F A. This accounts for 6 people. We have 8 people in total. The remaining two spots must be filled by C, E, and H.
The current arrangement is: B (P1) _ (P2) D (P3) G (P4) F (P5) A (P6). The remaining two spots are P7 and P8. Since it's a circular table, P8 would be to the immediate left of B (P1), and P7 would be between A (P6) and P8.
Let's visualize the circular arrangement (clockwise):
B - ? - D - G - F - A - ? - ? (back to B)
The two empty spots are between A and B.
Clue 3: C is not a neighbour of B or E.
From our sequence: B (P1) _ (P2) D (P3) G (P4) F (P5) A (P6). The remaining spots are P7 (between A and the last person) and P8 (between the last person and B).
The people left are C, E, H. There are two empty spots. This means one of C, E, H is already placed, which is not true. Let's re-evaluate the number of empty spots.
We have 6 people placed: B, D, G, F, A. This means 2 people are remaining (C, E, H). Wait, there are 8 friends. So 3 people are remaining.
Let's draw the circle and place them:
H/E/C
/ \
A B
| |
F ? (P2)
| |
G D
\ /
? (P7)
Let's restart the diagram with the established sequence: B _ D G F A. This sequence covers 6 positions. The remaining 2 positions (out of 8) must be filled by C, E, H. This is a contradiction, as there are 3 remaining people (C, E, H) but only 2 remaining spots. This means my interpretation of the sequence length was wrong.
Let's re-read: "A is second to the right of G who is third to the right of B."
1. Place B.
2. G is third to the right of B: B _ _ G.
3. A is second to the right of G: G _ A.
So, the arrangement is B (1) _ (2) _ (3) G (4) _ (5) A (6). This is 6 positions. There are 8 people. So 2 positions are left. Let's call them P7 and P8.
The circular arrangement (clockwise) is: B - P2 - P3 - G - P5 - A - P7 - P8 - B.
Now, "F sits between G and A." This means F is at P5.
Arrangement: B - P2 - P3 - G - F - A - P7 - P8 - B.
Now, "D is second to the left of F."
Arrangement: B - P2 - D - G - F - A - P7 - P8 - B.
The remaining people are C, E, H. The remaining spots are P2, P7, P8. This is still 3 people for 3 spots.
Now, "C is not a neighbour of B or E."
Arrangement: B - P2 - D - G - F - A - C - P8 - B.
If C is at P7, its neighbors are A (P6) and P8. So E cannot be at P8.
This means E must be at P2.
Arrangement: B - E - D - G - F - A - C - P8 - B.
So, H is at P8.
Final arrangement (clockwise): B - E - D - G - F - A - C - H - B.
Answer the question: Who is to the immediate left of B?
Looking at the final arrangement, the person immediately to the left of B (anti-clockwise) is H.
A) H is to the immediate left of B, as determined by the final arrangement: B - E - D - G - F - A - C - H (clockwise). Therefore, H is immediately to the left of B.
In which city was the 10th Biennial International Exhibition and Conference "India Chem 2018" held?

This question tests knowledge of the division of taxation powers between the Central and State Governments in India, as outlined in the Indian Constitution. Understanding which taxes are exclusively levied, collected, and retained by the Union (Central) Government is key.
Corporate tax (or Corporation Tax) is levied on the net income or profit of corporate entities. According to the Indian Constitution, specifically Entry 85 of the Union List (List I) in the Seventh Schedule, taxes on the income of corporations are exclusively within the legislative competence of the Central Government. Therefore, corporate tax is levied, collected, and retained by the Central Government.
