(C) The gases evolved in the reactions are:$(a)$ $CO_2$: Structure is $O=C=O$. It has $2 \sigma$ and $2 \pi$ bonds. (Equal)$(b)$ $SO_3$: Structure is $O=S(=O)_2$. It has $3 \sigma$ and $3 \pi$ bonds. (Equal)$(c)$ $SO_2$ $(2 \sigma, 1 \pi)$ and $SO_3$ $(3 \sigma, 3 \pi)$.$(d)$ $N_2$: Structure is $N \equiv N$. It has $1 \sigma$ and $2 \pi$ bonds. (Not equal)$(e)$ $SO_3$: Structure is $O=S(=O)_2$. It has $3 \sigma$ and $3 \pi$ bonds. (Equal)$(f)$ $NH_3$ $(3 \sigma, 0 \pi)$ and $HCl$ $(1 \sigma, 0 \pi)$.Thus,the reactions evolving gases with an equal number of $\sigma$ and $\pi$ bonds are $(a)$,$(b)$,$(c)$,and $(e)$.

Column $I$ (Molecules)	Column $II$ (Number of lone pairs on central atom)
$A. \ NH_3$	$1. \ \text{Two}$
$B. \ H_2O$	$2. \ \text{Three}$
$C. \ XeF_2$	$3. \ \text{Zero}$
$D. \ CH_4$	$4. \ \text{Four}$
	$5. \ \text{One}$
