(B) The reduction half-reaction for permanganate $(MnO_4^-)$ to manganese dioxide $(MnO_2)$ in an acidic medium is given by:$MnO_4^- + 4H^+ + 3e^- \longrightarrow MnO_2 + 2H_2O$In this reaction,the oxidation state of manganese changes from $+7$ in $MnO_4^-$ to $+4$ in $MnO_2$.The change in oxidation state is $7 - 4 = 3$.Therefore,$3$ electrons are involved in the reduction process.
