- DOzone is a form of oxygen in which three oxygen atoms are bounded together.
Explanation
Ozone is concentrated in the 15-55 km band of the atmosphere, is formed by photochemical reactions of oxygen, and is O3 — three oxygen atoms bonded together — so statements A, B and D are correct. The International Day for the Preservation of the Ozone Layer is observed on 16 September (the anniversary of the Montreal Protocol), not 16 November. Statement C is not correct.
