I gave my students this multiple choice question: Which of these best describes a species?

Only one answer is correct among these 4 choices:
- organisms that are similar in appearance
- organisms that adapt to similar environments
- organisms that can breed and produce fertile offspring
- organisms that live together in the same area

Could you tell me which one is correct?

organisms that can breed and produce fertile offspring
