Solution

The correct option is B $S O_{3}^{2 -}$
The reaction is $B a {C l}_{2} + H_{2} S O_{3} ⟶ B a S O_{3} + 2 H C l$

This barium sulphite is a white ppt.
The acid radical from equation may be ${S O}_{3}^{2 -}$ .

On dissolving in $H C l$ solution :

$B a S O_{3} + 2 H C l ⟶ B a C l_{2} + S O_{2} + H_{2} O$

$S O_{2}$ gas produce pungent smell
