But Fe is nonmetal, right?

It can also be Na.

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

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

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 a anthode while cu is a cathode.

Reduction potential of Fe is higher than that of Cu.

Fe is more reactive than cu thats why cu is displace from copper sulpate solution and thus formation of ferrous sulphate solution is made containing brown colour of doposit layer.

Iron(Fe) is the right answer as Fe is more reactive than Cu.When Fe reacts with CuSo4(cupper sulphate) solution ,it gives ferrous sulphate (FeSo4) and Cu will be deposited.
CuSo4 + Fe-------> FeSo4 + Cu.
CuSo4 + Fe-------> FeSo4 + Cu.

Fe is the right answer because ferrous is more reactive than copper due to which it will displace the copper from copper sulphate solution and the solution will become green in color due to the formation of ferrous sulphate and a brown layer of deposit layer will form on the iron metal.
