I gave my students this multiple choice question: A class is modeling the differences between a unicellular organism and a multicellular organism. Which example is a model of a unicellular organism?

Only one answer is correct among these 4 choices:
- a student passing out water to a group
- a student getting cereal from the cabinet
- two students collecting trash from a group
- four students working together to move a desk

Could you tell me which one is correct?
