Refer the electrochemical series position of both the copper. So the answer is iron.

Iron is less reactive than Cu according to the reactivity series table.
That is why iron is used to recover in the copper sulphate solution.

According to metal activity series, Fe is more reactive than Cu that means no reaction should take place and a less reactive element cannot replace a more reactive element and hence no reaction should take place. Then how come Cu replaces Fe?

cuso4+fe = cu+feso4.
Ferrous sulphate formula feso4.
Sodium sulphate formula na2so4.
Silver sulphate formula ag2so4.
Mercury (hg) is not metal is acid.
So answer is fe.

@Eliza.
The most electronegative elements are nonmetals.

I hold Fe as the answer; since Fe is found above Cu in the electrochemical series, it will displace Cu from CuSO4 to give FeSO4 and metallic Cu.
We talk of the electrochemical or reactivity series instead of electromagnetic series.
Thanks for your various proposed answers.
Fe + CuSO4 --------- = FeSO4 + Cu.

Fe + CuSO4 --------- = FeSO4 + Cu.

It is the most electronegative element.

Wonderful study on research about fe.

If Fe is more reactive than Cu then Na is also more reactive than Cu. So why cannot we use Na to get Cu from copper sulphate solution.

Any element higher than copper in the electrochemical series table will displace copper i.e. not copper itself.
