Solution

The correct option is B $S O_{3}^{-}, S O_{2}$
Solution
Reactions are
$(S O_{3})^{2 -} + H_{2} S O_{4} = S O_{2}$
$S O_{2} + K_{2} C r_{2} O_{7} + H_{2} S O_{4} = C r_{2} (S O_{4})_{3}$
$S O_{2}$ is colourless gas with irritating smell
$C r_{2} (S O_{4})_{3}$ is green colour solution
X = $(S O_{3})^{2 -}$
Y= $S O_{2}$
The correct option is A
