(D) The balanced chemical equation for the reaction in acidic medium is: $10I^{-} + 2MnO_4^{-} + 16H^{+} \rightarrow 5I_2 + 2Mn^{2+} + 8H_2O$. In $KMnO_4$,the oxidation state of $Mn$ is calculated as: $x + 1(-2) = -1 \Rightarrow x = +7$. In the product $Mn^{2+}$,the oxidation state of $Mn$ is $+2$. The change in the oxidation number of manganese is $|(+2) - (+7)| = 5$ units.
