Solution

The correct option is C
Light green solution of iron sulphate is obtained.

Iron metal is more reactive than copper and displaces it from copper sulphate solution (CuSO4). The deep blue colour of copper sulphate solution fades due to the formation of light green solution of iron sulphate.
