(B) In an acidic medium,the permanganate ion $(MnO_4^-)$ acts as a strong oxidizing agent.During the reduction process,the manganese atom in the $+7$ oxidation state gains $5$ electrons to be reduced to the $+2$ oxidation state.The balanced half-reaction is: $MnO_4^- + 8H^+ + 5e^- \rightarrow Mn^{2+} + 4H_2O$.Therefore,the product formed is $Mn^{2+}$.
