Solution

The correct option is C 1, 1, 1, 1, 2
The unbalanced chemical equation is
$A s O_{3}^{3 -} + I_{2} \to A s O_{4}^{3 -} + I^{-}$
Balance all atoms except H and O.
$A s O_{3}^{3 -} + I_{2} \to A s O_{4}^{3 -} + 2 I^{-}$
The oxidation number of As changes from +3 to +5. The net change in the oxidation number is 2.
The oxidation number of iodine changes from 0 to -1. The net change in the oxidation number per I atom is 1.
Total change in the oxidation number for 2 I atoms is 2.
Thus, the increase in the oxidation number is equal to the decrease in the oxidation number.
Balance O atoms by adding 1 water molecule to LHS.
$A s O_{3}^{3 -} + I_{2} + H_{2} O \to A s O_{4}^{3 -} + 2 I^{-}$
Balance H atoms by adding 2 $H^{+}$ to the RHS.
$A s O_{3}^{3 -} + I_{2} + H_{2} O \to A s O_{4}^{3 -} + 2 I^{-} + 2 H^{+}$
This is the balanced chemical equation.
Thus, he value of a, b, c, d & e respectively are 1, 1, 1, 1, 2.
