Answer 1

Sun is the ultimate source of energy of fossil fuels".

Fossil fuels are nothing but decomposed plant and animal matter which under the action of intense pressure and temperatures over millions of years produced coal, oil etc.

These plants and animals however survived on Earth due light received from the Sun (an other things as well). Sunlight helps in sustaining plant life (photosynthesis) and animals as well, animals being dependent on plants for al lot of things.

Thus, we can owe the very existence of fossil fuels to the Sun.

so option c is correct
