Consider the given sequence of reactions,

$$ \mathrm{C}_2 \mathrm{H}_6+\frac{3}{2} \mathrm{O}_2 \xrightarrow[\Delta]{(\mathrm{CH}, \mathrm{COO})_2 \mathrm{Mn}} X \xrightarrow{\mathrm{Na}} Y $$

Electrolysis of aqueous solution of $Y$ gives gases $P$ and $Q$ at anode. $P$ and $Q$ are respectively

$\mathrm{C}_2 \mathrm{H}_6, \mathrm{CO}_2$

$\mathrm{CH}_4, \mathrm{CO}_2$

$\mathrm{C}_2 \mathrm{H}_6, \mathrm{H}_2$

$\mathrm{CH}_4, \mathrm{CO}$
