Oxidation state of mercury can be +2, why can't be Hg then?

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.

Iron oxidation state is two so iron accept sulphate ion according to mechanism.

Fe is more reactive than Cu, and so will displace copper in solution.

Its a simple case of displacement reaction where, Fe being more reactive in the activity series of metal, replaces Cu from the CuSO4 solution to liberate free Cu.
Fe (more reactive) +CuSO4-->FeSO4 + Cu (less reactive).
Fe (more reactive) +CuSO4-->FeSO4 + Cu (less reactive).

Its because iron displaces copper sulphate as iron is more reactive metal than copper.

According to activity series, iron is more reactive then copper hence iron will displace copper from its aqueous solution.

Fe is high reactive than cu.

cuso4+Fe=Feso4+cu This is chemical reaction. cu give 2+ electron and so4 accept this electron.

Dolly in a mechanism iron easily produce 2e- and copper easily gain 2e-. And sodium produce only one electron so mechanism not set so iron is right answer.
