CFCs or chlorofluorocarbons are chemical substances made up of carbon, fluorine and chlorine atoms, belonging to the group of halocarbons, so they are not toxic or flammable. They were previously used in the manufacture of aerosols, refrigerants, blowing agent for foams and packaging material, as well as in solvents. Their use is currently prohibited due to the damage they cause to the environment.
CFCs are volatile compounds that, upon reaching the stratosphere, react with ultraviolet radiation. When interacting with radiation, chlorofluorocarbons release inorganic chlorine. The chlorine atoms released catalyze the conversion of ozone molecules into oxygen, this is why CFCs are associated with the destruction of the ozone layer.
Therefore the answer will be:
Answer: B. Chemical that destroys the ozone layer in earth’s atmosphere
