I gave my students this multiple choice question: Which features are physical properties of an iron nail?

Only one answer is correct among these 4 choices:
- conducts heat, magnetic, solid
- conducts electricity, magnetic, rusts
- conducts sound, insulates, non-magnetic
- dissolves, conducts heat, non-magnetic

Could you tell me which one is correct?
