in an experiment each of the metals Al Zn, Cu and Fe are reacted with ZnSO4.
CuSO4, Al2 (SO4)3 and FeSO4, solutions. The results are tabulated as follows
wheremeans that the reaction occurs and X means no reaction occurs.

On the basis of the above result the order of the reactivity of the metals may be
concluded as:
(a) Zn> Fe > Al > Cu
(b) Al > Fe> Zn > Cu
(c) Zn > Al>Fe > Cu
(d) Al > Zn> Fe > Cu

Answer 1

it is (d)Al > Zn> Fe > Cu

hope this helps :D
