• A. Heat rays only
• B. Visible light only
• C. Heat and visible light
• D. None of these

Answer 1

The correct option is C

Heat and visible light

Explanation of correct option:

1. Solar energy surface is mostly in the form of heat and visible light which is broadly called electromagnetic radiation.
2. As the sun is at a great distance from the surface of the earth the enormous energy developed in it due to fusion reaction only a fraction of it is able to reach the surface of the Earth.

Thus, solar energy reaching the surface of the earth is mostly in the form of heat and visible light.

Hence, option C is the correct answer.
