The correct option is D All of these
The green-house effect is the phenomenon in which the earth's traps the heat of sunlight reflected from the surface of the earth and prevent it from escaping. The phenomenon is named so because earth's atmosphere acts like a green-house made up of glass in which sunlight enters through transparent glass, but the heat is not allowed to escape. The green-house effect is also referred as global warming. Ozone depletion occurs when chlorofluorocarbons are released into the atmosphere. These gases, through several chemical reactions, cause the ozone molecules to break down, reducing the ultraviolet (UV) radiation absorbing capacity of ozone.
