The correct answer is:
$\mathrm{NaHCO}_{3}$
$2 \mathrm{NaHCO}_{3} \stackrel{\Delta}{\longrightarrow} \mathrm{Na}_{2} \mathrm{CO}_{3}+\mathrm{H}_{2} \mathrm{O}+\mathrm{CO}_{2}$
$\%$ of $\mathrm{C}=\frac{12}{84} \times 100=14.28 \%$
This Question can be done by checking $\%$ of carbon $14.2 \%$ comes only in $\mathrm{NaHCO}_{3}$
