The speed of sound in air is dependent on temperature. We need to recall the standard formula or common values for the speed of sound at different temperatures, particularly at 0°C and how it changes with each degree Celsius.
Correct Option: D) 346 m/s. This value is derived from the standard formula for the speed of sound in air, which increases by approximately \(0.6 \, \text{m/s}\) for every 1°C rise above 0°C (where it is about \(331 \, \text{m/s}\)). So, at 25°C, the speed would be \(331 + (25 \times 0.6) = 331 + 15 = 346 \, \text{m/s}\).
The question asks to identify the element responsible for photosynthesis in plants. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. We need to recall the key components and elements involved in this process.
C) Magnesium — Magnesium is the central metal ion in the chlorophyll molecule, which is essential for absorbing light energy during photosynthesis. Without magnesium, chlorophyll cannot be formed, and thus photosynthesis cannot occur.
