Solution
The correct option is D 25 km
The ozone layer is present in the stratosphere above the Earth. The layer is present at a distance of about 20-30 km away from the surface of the Earth. The layer of ozone is responsible for the absorption of the harmful UV radiations from the solar radiations. These radiations are prevented from entering the Earth's atmosphere to prevent the development of skin cancer. Thus, the correct answer is option D.
