The correct answer is:
$\mathrm{CO}_2, \mathrm{SO}_2, \mathrm{H}_2 \mathrm{O}$
When $\mathrm{H}_2 \mathrm{SO}_4$ (conc) react with non-metals, it
give oxoacid of non-metal and $\mathrm{SO}_2(\mathrm{~g})$. If oxoacid is unstable, it decomposes, [as in $\mathrm{H}_2 \mathrm{CO}_3$, which decomposes as $\mathrm{CO}_2+\mathrm{H}_2 \mathrm{O}$ ] the whole reaction occurs as follows :
$\mathrm{C}+\mathrm{H}_2 \mathrm{SO}_4 \stackrel{\Delta}{\longrightarrow} \mathrm{H}_2 \mathrm{CO}_3+\mathrm{SO}_2 \rightarrow \mathrm{CO}_2+\mathrm{H}_2 \mathrm{O}+\mathrm{SO}_2$
Hence, option (b) is the correct answer.
