I gave my students this multiple choice question: Which structures are common to both plant and animal cells?

Only one answer is correct among these 4 choices:
- vacuole, chloroplast, nucleus
- cell membrane, nucleus, mitochondrion
- nucleus, cell wall, cell membrane
- mitochondrion, vacuole, cell wall

Could you tell me which one is correct?
