I gave my students this multiple choice question: Which characteristic of a plant would best help it survive in a very dry climate?

Only one answer is correct among these 4 choices:
- colorful flowers to attract insects
- strong stems to stay upright
- waxy leaves to keep in water
- green color to photosynthesize

Could you tell me which one is correct?

waxy leaves to keep in water
