I gave my students this multiple choice question: Which organisms benefit in the relationship between bees and flowering plants?

Only one answer is correct among these 4 choices:
- only the bees
- only the flowering plants
- both the bees and the flowering plants
- neither the bees nor the flowering plants

Could you tell me which one is correct?

both the bees and the flowering plants
