Solution

The correct option is B Harmful radiations of sun
Ozone layer is a region of concentration of ozone molecule, O3(O2 +O) in the earth's atmosphere. The layer lies in the stratosphere at an altitude of 18-50 kms. The ozone layer naturally shields earth's life from the harmful effect of the Sun's ultraviolet radiations.
