When a strip of copper is placed in aqueous silver nitrate, a displacement reaction takes place. What is the ionic equation for the reaction which takes place?

1. AAg+(aq) + Cu(s) → Ag(s) + Cu2+(aq) + e–
2. B2Ag+(aq) + Cu(s) → 2Ag(s) + Cu2+(aq)
3. C2AgNO3(aq) + Cu(s) → 2Ag(s) + Cu(NO3)2(aq)
4. D2Ag(s) + Cu2+(aq) → 2Ag+(aq) + Cu(s)
