The correct answer is:
If both assertion and reason are true but reason is not the correct explanation of assertion
$\mathrm{SO}_2$ shows both oxidising as well as reducing nature.
The reaction given in assertion is due to oxidising nature of $\mathrm{SO}_2$.
$$
2 \mathrm{H}_2 \mathrm{~S}+\mathrm{SO}_2 \rightarrow 2 \mathrm{H}_2 \mathrm{O}+3 \mathrm{~S}
$$
The reaction given in assertion is due to oxidising nature of $\mathrm{SO}_2$.
$$
2 \mathrm{H}_2 \mathrm{~S}+\mathrm{SO}_2 \rightarrow 2 \mathrm{H}_2 \mathrm{O}+3 \mathrm{~S}
$$
