Comprehension XIV
Gaseous substances \( (\mathrm{CHO})_{p} \) and \( (\mathrm{COOH})_{q} \), when heated, decompose according to the following reactions.
\[
\begin{aligned}
(\mathrm{CHO})_{p} & \rightarrow \mathrm{CO}+\mathrm{H}_{2} \\
(\mathrm{COOH})_{q} & \rightarrow \mathrm{CO}_{2}+\mathrm{H}_{2}
\end{aligned}
\]
A volume of \( 10 \mathrm{ml} \) of mixture containing \( (\mathrm{CHO})_{\mathrm{p}} \) and \( (\mathrm{COOH})_{q} \) in 1:4 mole ratio was heated for complete decomposition. The resulting gases when passed through \( \mathrm{KOH} \), the volume decrease to \( 9 / 17^{\text {th }} \) of the volume of gaseous mixture passed. Remaining gases on complete combustion showed a contraction of \( 61 \mathrm{ml} \).
The values of \( p \) and \( q \) are
(a) \( p=10, q=6 \)
(b) \( p=6, q=10 \)
(c) \( p=3, q=5 \)
(d) \( p=5, q=3 \)
