I gave my students this multiple choice question: Sunlight is able to penetrate the top several meters of marine water, where most plant and animal life exists. Which of these systems are interacting in this description?

Only one answer is correct among these 4 choices:
- solar energy and ocean systems
- solar energy and weather systems
- weather systems and ocean systems
- solar energy, ocean systems, and weather systems

Could you tell me which one is correct?
