A. The use of freon and CFC spray propellants.
Chlorofluorocarbons (CFCs) and similar substances have been identified as the primary contributors to ozone layer depletion. When released into the atmosphere, CFCs rise and eventually reach the stratosphere, where they are broken down by ultraviolet (UV) radiation, releasing chlorine atoms that then contribute to the destruction of ozone molecules.
