Ozone in stratosphere is depleted by

Step-by-step solution

The depletion of the ozone layer in the stratosphere is primarily caused by chlorofluorocarbons (CFCs). CFCs are compounds containing chlorine, fluorine, and carbon. When these compounds reach the stratosphere, they are decomposed by ultraviolet radiation to release chlorine free radicals ( Cl ^ ). The chlorine radical acts as a catalyst in the destruction of ozone ( O ₃ ) through the following reactions: Cl ^ + O ₃ ClO ^ + O ₂ ClO ^ + O Cl ^ + O ₂ Among the given options, CF ₂ Cl ₂ (dichlorodifluoromethane, common
