Solution

The correct option is A ${MnO}_{2}$
The substance is said to be reduced if it gains hydrogen, loses oxygen or gains electrons.
In the above reaction, ${MnO}_{2}$ (manganese dioxide) is transformed to ${MnCl}_{2}$ (manganese chloride) by gaining electrons.
${Mn}^{4 +} + 2 e^{-} \to {Mn}^{2 +}$
Therefore, ${MnO}_{2}$ is getting reduced.
