Solution

The correct option is D $2 S b C l_{3} + K l O_{3} + 6 H C l \to 2 S b C l_{5} + I C l + 3 H_{2} O + K C l$
The unbalanced redox equation is as follows:
$S b C l_{3} + K I O_{3} + H C l \to S b C l_{5} + I C l + H_{2} O + K C l$
Balance all atoms other than H and O.
$S b C l_{3} + K I O_{3} + 4 H C l \to S b C l_{5} + I C l + H_{2} O + K C l$
The oxidation number of Sb changes from 3 to 5. The change in the oxidation number of Sb is 2.
The oxidation number of I changes from 5 to 1. The change in the oxidation number of I is 4.
The increase in the oxidation number is balanced with decrease in the oxidation number by multiplying
$S b C l_{3}$ and $S b C l_{5}$ with 2. Also balance Cl atoms.
$2 S b C l_{3} + K I O_{3} + 6 H C l \to 2 S b C l_{5} + I C l + H_{2} O + K C l$
O atoms are balanced by adding 2 water molecules on RHS.
$2 S b C l_{3} + K I O_{3} + 6 H C l \to 2 S b C l_{5} + I C l + 2 H_{2} O + K C l$
Hydrogen atoms are balanced.
$2 S b C l_{3} + K I O_{3} + 6 H C l \to 2 S b C l_{5} + I C l + 3 H_{2} O + K C l$
This is the balanced chemical equation.
