D Correct answer
Explanation

Ozone layer is a sub layer of Stratosphere. It is in the lower stratosphere, from 6 to 25 miles above the ground. There is also ozone present in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the Sun's ultraviolet radiation. Without this layer, life on earth would be very difficult.
