c. CFCs
Explanation:
CFCs (chlorofluorocarbons) are the gases responsible for the depletion of the ozone layer. When released into the atmosphere, CFCs eventually reach the stratosphere, where they are broken down by ultraviolet (UV) light, releasing chlorine atoms. These chlorine atoms then react with ozone (O3) molecules, leading to the depletion of the ozone layer. Â
