(C) In acidic medium, $KMnO_4$ (i.e.,$MnO_4^-$) undergoes reduction to $Mn^{2+}$ as follows: $MnO_4^- + 8H^+ + 5e^- \longrightarrow Mn^{2+} + 4H_2O$ Here, the change in oxidation state of $Mn$ is from $+7$ to $+2$, so the number of electrons gained ($n$-factor) is $5$. Equivalent weight $= \frac{\text{Molecular weight}}{n\text{-factor}} = \frac{158}{5} = 31.6 \ g$.
