Cl ˙ + CH 4 → A + B A and B in the above atmospheric reaction step are

$\dot{Cl} + {CH}_{4} \to A + B$

$A$ and $B$ in the above atmospheric reaction step are

$C_{2} H_{6}$ and ${Cl}_{2}$
$\dot{C} {HCl}_{2}$ and $H_{2}$
$\dot{{CH}_{3}}$ and $HCl$
$C_{2} H_{6}$ and $HCl$

Solution

In summer season, chlorine atoms forming chlorine sinks, preventing much ozone depletion, whereas In winter, special type of clouds called polar stratospheric clouds are formed over Antarctica.
$\overset{•}{C} l (g) + {CH}_{4} (g) \to \overset{•}{C} H_{3} (g) + HCl (g)$
