Solution

The correct option is C
Zinc is the most reactive metal out of zinc, copper and iron.

In the first reaction, Fe displaces Cu. Therefore, Fe is more reactive than Cu (reactivity of Fe> reactivity of Cu).

In the second reaction Fe is displaced by Zn. Therefore, Fe is less reactive than Zn (reactivity of Zn> reactivity of Fe).

Therefore, Zn is more reactive and Cu is least reactive.
