I gave my students this multiple choice question: How is a skin cell from a mouse similar to an amoeba?

Only one answer is correct among these 4 choices:
- Both need energy.
- Both have cell walls.
- Both move with pseudopodia.
- Both consume carbon dioxide.

Could you tell me which one is correct?

Both need energy.
