Vedclass · Answer

(C) The correct answer is $(C)$. Chlorofluorocarbons $(CFCs)$ are stable, non-toxic, and non-flammable chemicals that were widely used in refrigerators, air conditioners, and aerosol sprays. When $CFCs$ reach the stratosphere, they are broken down by ultraviolet $(UV)$ radiation, releasing chlorine atoms. These chlorine atoms act as catalysts in the breakdown of ozone $(O_3)$ molecules into oxygen $(O_2)$, leading to the depletion of the ozone layer.
