The ozone layer protects us from
A
Radio waves
B
Visual radiation
C
Ultra violet rays
D
Infrared radiation
Explanation: 

Detailed explanation-1: -The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer.

Detailed explanation-2: -Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called ‘good’ ozone. This is in contrast to ozone in the troposphere, the lowest layer of the atmosphere, where it is an air pollutant and can be harmful to humans, animals and vegetation.

Detailed explanation-3: -The ozone layer acts as an invisible shield and protects us from harmful ultraviolet (UV) radiation from the sun. In particular, the ozone layer protects us from the UV radiation, known as UV-B, which causes sunburn.

Detailed explanation-4: -It absorbs most of the sun’s ultraviolet radiation (UV-B), limiting the amount of this radiation that reaches the surface of the Earth. Because this radiation causes skin cancer and cataracts, the ozone layer plays an important role in protecting human health.
