The main function of the ozone layer is to block most of the sun's damaging rays from reaching Earth.
Option: (b)
<u>Explanation:</u>
The stratosphere containing high level of ozone molecules about 30 km to 50 km altitude helps to absorb the sun's ultra violate rays.
In its absence, it would be very difficult for anything to survive. Plants cannot live and grow as the UV light causes weakening of plants.
It causes skin cancers. The increase in UV flux will lead to increase in sunburn, blindness, cataract, causing potentially death of animals and plants.
