Correct option is D
Chlorofluorocarbons (CFCs) are synthetic compounds containing
chlorine (Cl), fluorine (F), and carbon (C).
When released into the atmosphere,
CFCs rise to the stratosphere and undergo photodissociation by ultraviolet (UV) radiation, releasing chlorine atoms.
These chlorine atoms catalytically break down
ozone (O₃) molecules, depleting the ozone layer, which protects Earth from harmful UV radiation.
