Solution

The correct option is C $Z n + M g S O_{4} \to Z n S O_{4} + M g$
The reactivity series is a list of metals arranged in the order of their decreasing activities. Zn comes after Mg in the reactivity series. Hence, zinc cannot displace magnesium from magnesium sulfate and reaction is not possible.
