Solution
The correct option is A CuSO4+Fe
According to the reactivity series of metals, more reactive metal can displace less reactive metal from its salt solution.
As can be seen from the reactivity series of metals, iron is more reactive than copper and hence iron can displace copper from its salt solution (CuSO4).
The reaction takes place as:
CuSO4+Fe→FeSO4+Cu
Zn, Mg and Ca are more reactive than Fe, hence Fe cannot displace these metals from their salt solution.
