Any element higher than copper in the electrochemical series table will displace copper i.e. not copper itself.

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.

Fe lies above cu in metal activity series so it simply displaces cuso4.

It's simple displacement reaction.
cuso4+fe ->feso4+cu.
cuso4+fe ->feso4+cu.

Why Fe has more reduction power then Cu ?
Fe _ [Ar]18 3d6 4s2 & Cu_ [Ar]18 3d10 4s1.
So the reduction power of Fe is more then cu, as reduction power is nothing but ability to gain electron.
Fe _ [Ar]18 3d6 4s2 & Cu_ [Ar]18 3d10 4s1.

Fe, it because of electrochemical series.

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.

Na reacts violently with water, and the kinetics with which the reaction proceeds will be hard to control. So the most practical answer would be Fe.

Good, I like this. Thanks all for explaining.

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