Q. Complete the following reactions.
(i) $M n O_{4}^{-} + 2 H_{2} O + 3 e^{-} \to$ ___ + $4 O H^{-}$
(ii) $M n O_{4}^{-} + 8 H^{+} + 5 e^{-} \to$ ____ $+ 4 H_{2} O$
(iii) $M n O_{4}^{-} + e^{-} \to$ ____

$M n O_{2}$ , $M n^{2 +}$ , $M n O_{4}^{2 -}$

$M n^{2 +}$ , $M n O_{2}$ , $M n O_{4}^{2 -}$

$M n O_{4}^{2 -}$ , $M n^{2 +}$ , $M n O_{2}$

$M n O_{2}$ , $M n O_{4}^{2 -}$ , $M n^{2 +}$

$M n O_{4}^{-} + 2 H_{2} O + 3 e^{-} \to M n O_{2} + 4 O H^{-}$
$M n O_{4}^{-} + 8 H^{+} + 5 e^{-} \to M n^{2 +} + 4 H_{2} O$
$M n O_{4}^{-} + e^{-} \to M n O_{4}^{2 -}$
