The question asks about the primary function of insulin in the human body. To answer this, we need to recall the role of insulin as a hormone in metabolic regulation.
Based on this understanding, we can evaluate the given options.
Correct Option: A) It regulates how the body uses and stores glucose and fat.
This statement accurately describes the multifaceted role of insulin. Insulin facilitates the uptake of glucose by cells, promoting its use for energy or storage as glycogen or fat. It also influences fat metabolism by encouraging fat storage and preventing its release from adipose tissue.

The question asks about the origin of the constitutional provision for the indirect election of Rajya Sabha members in India. This is a direct factual question related to the sources of the Indian Constitution, a common topic in Indian competitive exams.
B) South Africa — The Indian Constitution adopted the method of indirect election of members to the Rajya Sabha, based on proportional representation by means of the single transferable vote, from the Constitution of South Africa. South Africa also contributed the procedure for constitutional amendment.
A box contains 6 white balls and 7 black balls. Two balls are drawn at random. What is the probability that both of them are of different colours?
\( \frac{4}{13} \)
\( \frac{2}{13} \)
\( \frac{6}{13} \)
\( \frac{7}{13} \)
To find the probability that two randomly drawn balls are of different colors, we will first calculate the total number of ways to draw two balls from the box. Then, we will calculate the number of ways to draw one white ball and one black ball. Finally, we will divide the number of favorable outcomes by the total number of outcomes.
This is a combination problem, as the order of drawing balls does not matter. The total number of ways to choose 2 balls from 13 is given by \(^{13}C_2\).
\[ ^{13}C_2 = \frac{13!}{2!(13-2)!} = \frac{13!}{2!11!} = \frac{13 \times 12}{2 \times 1} = 13 \times 6 = 78 \]This means drawing one white ball AND one black ball. The number of ways to choose 1 white ball from 6 is \(^6C_1\), and the number of ways to choose 1 black ball from 7 is \(^7C_1\).
The number of ways to draw one white and one black ball is the product of these two numbers:
\[ \text{Favorable outcomes} = ^6C_1 \times ^7C_1 = 6 \times 7 = 42 \]The probability of drawing two balls of different colors is the ratio of favorable outcomes to the total number of outcomes.
\[ P(\text{different colors}) = \frac{\text{Favorable outcomes}}{\text{Total outcomes}} = \frac{42}{78} \]Both 42 and 78 are divisible by 6.
\[ P(\text{different colors}) = \frac{42 \div 6}{78 \div 6} = \frac{7}{13} \]D) \( \frac{7}{13} \) is the correct probability, as calculated.
