C Correct answer
Explanation

Chlorofluorocarbons (CFCs) are the primary chemicals responsible for ozone layer depletion. When CFCs reach the stratosphere, UV radiation breaks them down and releases chlorine atoms, which catalytically destroy ozone molecules. This led to the Montreal Protocol banning CFC production. CO2 causes climate change, not ozone depletion.
