Question

volcanic
water
air
land
which type of pollution includes cfcs and smog?

Explanation:

CFCs (Chlorofluorocarbons) and smog are pollutants that exist in the atmosphere. Air pollution includes contaminants like CFCs (which deplete the ozone layer) and smog (formed from air pollutants reacting in the atmosphere). Land pollution relates to contaminants on land, water pollution to water bodies, and volcanic is a natural process not a pollution type category here. So the pollution type with CFCs and smog is air pollution.

Answer:

air (the option corresponding to air pollution, as CFCs and smog are air pollutants)
