Answer

Brief Explanations:

Chlorofluorocarbons (CFCs) release chlorine atoms in the stratosphere. Free oxygen atoms can displace chlorine in chlorine - monoxide, releasing a free chlorine atom. This chlorine atom can react with ozone ($O_3$) and destroy it. CFCs do not act like UV radiation to produce ozone (a is wrong), chlorine from CFCs reacts with ozone not free oxygen molecules to stop ozone production (b is wrong), and CFCs do not absorb UV radiation to prevent ozone formation (d is wrong).

Answer:

C. Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone.
