Locking of chlorine monoxide and free radicals of chlorine is called SCAVENGING. In the atmosphere, nitrogen dioxide scavenges chlorine monoxide and methane scavenges chlorine atoms, which are responsible for:
P — Acid rain
Q — Global warming
R — Ozone depletion

Answer
Only R
Reason — In the atmosphere, nitrogen dioxide scavenges chlorine monoxide and methane scavenges chlorine atoms,
ClO (g) + NO2 (g) ⟶ ClONO2 (g)
Cl (g) + CH4 (g) ⟶ CH3 (g) + HCl (g)
The process continues and these free radicals continue to break ozone molecules, causing the depletion of ozone.
