A Correct answer
Explanation

Chlorofluorocarbons (CFCs) are synthetic compounds that break down in the stratosphere, releasing chlorine atoms that catalytically destroy ozone molecules. This led to the formation of the ozone hole. Oxides, sulphides, and hydroxides do not have this ozone-depleting effect.
