Correct choice is (b) Sun
 
The best I can explain: The only source of energy for all ecosystems on Earth is the sun. The radiant light and heat from the sun is the primary, original source for most of the organisms and is used for the production of electricity, fuel, thermal energy, agriculture, etc.
