I gave my students this multiple choice question: When can producers make the most food?

Only one answer is correct among these 4 choices:
- summer, because there is more sunlight
- summer, because there is more heat
- spring, because there is more rain
- spring, because there are more leaves

Could you tell me which one is correct?

summer, because there is more sunlight
