The correct answer is D. CFC.
CFCs are chlorofluorocarbons, which are man-made chemicals that were once widely used in refrigerators, air conditioners, and aerosol cans. CFCs are very stable and do not break down easily in the atmosphere. When they reach the stratosphere, they are broken down by ultraviolet radiation and release chlorine atoms. These chlorine atoms react with ozone molecules, destroying them.
CO2 is carbon dioxide, which is a natural gas that is released into the atmosphere when fossil fuels are burned. CO2 is a greenhouse gas, which means that it traps heat in the atmosphere and contributes to climate change.
SO2 is sulfur dioxide, which is a gas that
is released into the atmosphere when coal and oil are burned. SO2 can cause acid rain, which can damage forests and lakes.CO is carbon monoxide, which is a gas that is produced when gasoline is burned in an engine. CO is a poisonous gas that can cause death if inhaled in high concentrations.
CFCs are the main cause of ozone holes. Ozone holes are areas in the stratosphere where the ozone layer has been depleted. The ozone layer is a layer of gas in the stratosphere that protects the Earth from harmful ultraviolet radiation. Ozone holes can cause skin cancer and other health problems.
