(C) In the reaction $MnO_2 + 4HCl \to MnCl_2 + 2H_2O + Cl_2$:$1$. The oxidation state of $Mn$ in $MnO_2$ is $+4$ and in $MnCl_2$ is $+2$. Since the oxidation state decreases,$Mn^{4+}$ is reduced.$2$. The oxidation state of $Cl$ in $HCl$ is $-1$ and in $Cl_2$ is $0$. Since the oxidation state increases,$Cl^-$ is oxidised.Therefore,statements $(2)$ and $(3)$ are correct.
