As we have learnt,

During spring, sunlight breaks up polar stratosphere clouds and \mathrm{HOCl} and \mathrm{Cl_2} are photolysed to form Chlorine radicals. These Chlorine radicals thus formed promote ozone depletion.

\mathrm{HOCl\left ( g \right )\overset{hv}{\rightarrow}\dot{O}H\left ( g \right )+\dot {Cl}\left ( g \right )}

\mathrm{Cl_{2}\left ( g \right )\overset{hv}{\longrightarrow}2\dot{Cl}\left ( g \right )}

\mathrm{\dot{ C } 1( g )+ O _{3}( g ) \rightarrow Cl \dot{ O }( g )+ O _{2}( g )}

Hence, the correct answer is Option (4)
