I gave my students this multiple choice question: Pesticides are chemicals that kill insects. What could happen if the pesticides killed all the pollinators near some apple trees?

Only one answer is correct among these 4 choices:
- The trees could not make leaves.
- The trees could not make flowers.
- The trees could not make seeds.
- The trees could not make bark.

Could you tell me which one is correct?

The trees could not make seeds.
