1 Answer

Answer :

(2) Stratosphere Explanation: Most ozone (about 90%) resides in a layer that begins between 10 and 17 kilometers above the Earth's surface and extends up to about 50 kilometers. This region of the atmosphere is called the stratosphere. The ozone layer absorbs most of the Sun's ultraviolet (UV) radiation.
