I gave my students this multiple choice question: Which is most likely a cancer treatment?

Only one answer is correct among these 4 choices:
- a drug that kills only very small cells
- a drug that kills only very large cells
- a drug that kills only slowly dividing cells
- a drug that kills only rapidly dividing cells

Could you tell me which one is correct?
