Which pair correctly gives a gas and its main function?
Answer and explanation
Correct answer: Ozone — ultraviolet absorption
Ozone forms the protective ozone layer mainly in the stratosphere. Its important function is absorbing a large part of the Sun’s harmful ultraviolet radiation before that radiation reaches Earth’s surface. Therefore, option D correctly matches the gas with its function. Oxygen supports respiration, carbon dioxide is used in photosynthesis, and nitrogen and argon do not perform the functions stated in the other options. The governing concept is the role of atmospheric gases in protecting and supporting life.
