(B) The depletion of the ozone layer is primarily caused by chlorofluorocarbons $(CFCs)$.When $CFCs$ reach the stratosphere,they are broken down by ultraviolet $(UV)$ radiation,releasing chlorine atoms $(Cl)$.These chlorine atoms act as catalysts in the chemical reaction that converts ozone $(O_3)$ into oxygen $(O_2)$.One chlorine atom can destroy thousands of ozone molecules because it is not consumed in the reaction,thus acting as a catalyst.
