Answer 1

The main function of the ozone layer is to block most of the sun's damaging rays from reaching Earth.

Option: (b)

Step-by-step explanation:

• 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.
