I agree with @Tushar, @Preeti and @Lenhkp.
Its just because Fe is more reactive than Cu and so would displace the Cu in the reaction.

How please explain this question?

Fe is a anode and cu is a cathode.

Then Na also should have reduced Cu because it lies way ahead of Cu in the electrochemical series, just like Fe.

FE is high reactive than cu.

As the fe and cu both lying in the same group. And although the electronegativity of fe is higher than cu.

Cu is biggest molecule.

I Think Fe (Ferrum) will work best because it is not very reactive and yet it can displace copper from its sulphate. Sodium (NA or Natrium) can as well be used.

FE is iron then what is need?

Iron(Fe) is more reactive than Copper(Cu). So Iron displaces Copper from Copper sulfate(CuSO4) to form Iron sulfate(FeSO4).
