As we have learnt,

Breakdown of ozone 

CFCs in stratosphere absorbs UV radiations and form chlorine free radical, which continuously breakdown the ozone.

CF_{2}Cl_{2}(g)\rightarrow \dot{Cl}(g)+\dot{C}F_{2}Cl(g)

\dot{Cl}(g)+O_{3}\left ( g \right )\rightarrow Cl\dot{O}(g)+O_{2}(g)

Cl\dot{O}\left ( g \right )+\dot{O}\left ( g \right )\rightarrow \dot{Cl}\left ( g \right )+O_{2}\left ( g \right )

Hence, the correct answer is Option (2)
