Q. Which of the following equations is a balanced one?

$5 B i O_{3}^{-} + 22 H^{+} + M n^{2 +} \to 5 B i^{3 +} + 7 H_{2} O + M n O_{4}^{-}$

$5 B i O_{3}^{-} + 14 H^{+} + 2 M n^{2 +} \to 5 B i^{3 +} + 7 H_{2} O + 2 M n O_{4}^{-}$

$2 B i O_{3}^{-} + 4 H^{+} + M n^{2 +} \to 2 B i^{3 +} + 2 H_{2} O + M n O_{4}^{-}$

$6 B i O_{3}^{-} + 12 H^{+} + 3 M n^{2 +} \to 6 B i^{3 +} + 6 H_{2} O + 3 M n O_{4}^{-}$

$5 B i O_{3}^{-} + 2 M n^{2 +} \to 5 B i^{3 +} + 2 M n O_{4}^{-}$
$H$ and $O$ balance
$5 B i O_{3}^{-} + 2 M n^{2 +} + 14 H^{+} \to 5 B_{1}^{3 +} + 2 M n O_{4}^{-} + 7 H_{2} O$
