The incorrect statement about Ozone is : (1) Bad Ozone is present in Troposphere. (2) Ozone is responsible for greenhouse effect in Stratosphere. (3) Ozone is destroyed by chlorofluorocarbons in atmosphere. (4) Ozone shields the surface of the earth from harmful UV-radiation from the sun.

Statement (1) is correct: "Bad Ozone" or ground- level ozone, which is a pollutant, is primarily found in the troposphere. Statement (2) is incorrect. While ozone does absorb some terrestrial infrared radiation, its primary role in the stratosphere is to absorb UV radiation. The major greenhouse gases responsible for the greenhouse effect are water vapor, carbon dioxide, methane, and nitrous oxide. Ozone plays a minor role, if any, in the stratospheric greenhouse effect compared to its role in UV absorption. Statement (3) is correct: Chlorofluorocarbons (CFCs) and other halocarbons are known to catalytically destroy ozone molecules in the stratosphere. Statement (4) is correct: The ozone layer in the stratosphere absorbs most of the Sun's harmful ultraviolet (UV) radiation, protecting life on Earth.
