Option 3: Cu + PbCl2^ CuCl2 + Pb

This chemical reaction is not feasible because it violates the reactivity series. In the reactivity series, copper (Cu) is less reactive than lead (Pb). This means that copper cannot displace lead from lead chloride (PbCl2) to form copper chloride (CuCl2) and lead (Pb). When a more reactive metal comes into contact with a less reactive metal salt, the more reactive metal will displace the less reactive metal from the salt. However, in this case, copper cannot displace lead from lead chloride, making this reaction not feasible.

Option 1: Fe + CuSO4^ FeSO4 + Cu

This chemical reaction is feasible because iron (Fe) is more reactive than copper (Cu) according to the reactivity series. So, iron can displace copper from copper sulfate (CuSO4) to form iron sulfate (FeSO4) and copper.

Option 2: Zn + CuSO4^ ZnSO4 + Cu

This chemical reaction is also feasible because zinc (Zn) is more reactive than copper (Cu). Therefore, zinc can displace copper from copper sulfate to form zinc sulfate (ZnSO
