Question
Ozone is found in
✓
Answer
(a) The stratosphere or "good ozone" layer extends upward from about $6$ to $30$ miles and protects life on earth from the sun's harmful ultraviolet (UV) rays.
Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up $21 \%$ of the atmosphere.
So, the correct answer is 'Stratosphere.’
