Vedclass · Answer

(C) The depletion of the ozone layer in the stratosphere is primarily caused by substances that release chlorine or bromine radicals,such as chlorofluorocarbons $(CF_2Cl_2)$ and nitrogen oxides $(NO)$. $Cl_2$ can also contribute to ozone depletion through the release of chlorine atoms. $CH_4$ (methane) is a greenhouse gas,but it is not primarily responsible for the depletion of the ozone layer; in fact,it can react with chlorine radicals to form $HCl$,which helps in the removal of ozone-depleting chlorine species.
