The reaction series is as follows:
K Na Ca Mg Al Zn Fe Pb Cu Hg Ag Au
Since only Fe comes b4 copper, Fe can displace copper from the solution.
K Na Ca Mg Al Zn Fe Pb Cu Hg Ag Au
Since only Fe comes b4 copper, Fe can displace copper from the solution.

What is needed is a substance that can displace copper hence any substance more reactive than copper will work i.e an [aq] solution of sodium

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.

Fe is more electropositive that is more reactive that is a cause of decomposition rxn in which cu is displaced by Fe.
Cuso4 +fe =feso4 +cu.
Cuso4 +fe =feso4 +cu.

I think sodium is the right answer, as it is above iron in periodic which has greater ability to react with sulphate to displace copper.

Fe has great affinity to the sulphate ion that shows Fe replaces the copper ion the formation of compound FeSo4 or cu can be separated.

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.

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.

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

The chemical reaction of changing iron and copper sulphate to form iron sulphate and copper :
Fe + CuSO4 → FeSO4 + Cu
Fe + CuSO4 → FeSO4 + Cu
