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.

Fe is higher reactive than cu so it displaces fe in fe so4.

Fe is more electronegative than Cu so it will displace Cu according to displacement reaction.

It can also be Na.

But Fe is nonmetal, right?

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.

In the electrochemical series, Na is higher than Fe.
Na is should be the answer.
Na is should be the answer.

Ag & Hg are less reactive than copper.
Adding sodium - it would ignite before it could react.
Fe is more reactive than copper and would displace it to combine with the sulfate ion, thereby separating copper.

Fe is more reactive than copper so it reduces copper sulphate to copper.

A/c to electrochemical series, Iron is more reactive than Copper so it reduces Copper sulphate to get copper.
