There are two elements Na and Fe. Because both element is high level of metal activity series. Na is more react than Fe. But the answer is Fe. Because Na reacts with water. So it's not useful for recover than Fe.

Actually both sodium and iron are able to displace copper from its solution. Right?

In the activity series, iron is more reactive element than copper. So iron can separate copper from copper sulfate.

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

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.
