A Correct answer
Explanation

Chlorofluorocarbons (CFCs) are synthetic compounds that break down in the stratosphere and release chlorine atoms, which catalytically destroy ozone molecules. This depletion of the ozone layer allows more harmful UV radiation to reach Earth. Oxides, sulphides, and hydroxides are not responsible for ozone depletion.
