Solution

The correct option is C evolution of heat
Zinc is more reactive than iron. So when it is added to iron sulphate solution it displaces iron. The reaction involved is:

$Zn (s) + {FeSO}_{4} (aq) \to {ZnSO}_{4} (aq) + Fe(s) + Heat$

The colour of solution changes from green to colourless due to the formation of zinc sulphate. The reaction is exothermic in nature.
