Solution

The correct option is C $2 C l O_{2} + S b O_{2}^{-} + 2 H_{2} O + 2 O H^{-} \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-}$
$+ 4 C l O_{2} + + 3 S b O_{2}^{-} \to + 3 C l O_{2}^{-} + + 5 S b (O H)_{6}^{-}$

$C l O_{2}$ is an oxidising agent.
$S b O_{2}^{-}$ is a reducing agent.

$n_{f} = (| O . S ._{P r o d u c t} - O . S ._{R e a c t a n t} |) \times number of atom$

$+ 3 S b O_{2}^{-} \to + 5 S b (O H)_{6}^{-}$ oxidation
$n_{f} = (| + 5 - 3 |) \times 1 = 2$

$+ 4 C l O_{2} \to + 3 C l O_{2}^{-}$ reduction
$n_{f} = (| + 3 - 4 |) \times 1 = 1$

Ratio of $n_{f}$ for oxidation to reduction is $2 : 1$ .

Cross mutiplying the oxidising and reducing agents with ratio of n-factors.
$2 C l O_{2} + S b O_{2}^{-} \to C l O_{2}^{-} + S b (O H)_{6}^{-}$

Balancing elements except $O$ and $H$
$2 C l O_{2} + S b O_{2}^{-} \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-}$

Balancing oxygen by adding $H_{2} O$
$2 C l O_{2} + S b O_{2}^{-} + 4 H_{2} O \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-}$

Balancing hydrogen by adding $H^{+}$
$2 C l O_{2} + S b O_{2}^{-} + 4 H_{2} O \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-} + 2 H^{+}$

Adding $2 O H^{-}$ on both sides to balance in basic medium
$2 C l O_{2} + S b O_{2}^{-} + 4 H_{2} O + 2 O H^{-} \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-} + 2 H^{+} + 2 O H^{-}$

$2 C l O_{2} + S b O_{2}^{-} + 4 H_{2} O + 2 O H^{-} \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-} + 2 H_{2} O$

Canceling $H_{2} O$
$2 C l O_{2} + S b O_{2}^{-} + 2 H_{2} O + 2 O H^{-} \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-}$

Balancing charge:

charge in reactant side $= - 1 - 2 = - 3$
charge in product side $= - 2 - 1 = - 3$

So the balanced equation is
$2 C l O_{2} + S b O_{2}^{-} + 2 H_{2} O + 2 O H^{-} \to 2 C l O_{2}^{-} + S b (O H)_{6}^{-}$
