Explanation
Chloroflorocarbons are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They react with the ozone and destroy it, making the layer thinner and allowing ultraviolet (UV) radiation to pass through it and fall on the earth's surface. This UV radiation can cause skin cancer and other ailments in humans and also affect plants and animals. The main source of CFC production is Coal combustion i.e. burning of coal. Among the given options, option A is correct because, unlike the rest, CFCs are released into the atmosphere, not produced.
