Solution

The correct option is C Helps in checking the ultra violet rays to earth
Ultraviolet radiations are highly energetic radiations which may cause harmful mutagenic changes. The stratosphere present in the atmosphere contains ultraviolet radiation absorbs the harmful ultraviolet radiation and protects us from several chronic diseases. Only ozone effectively absorbs the most energetic ultraviolet light, known as UV-C and UV-B, which causes biological damage. The protective role of the ozone layer in the upper atmosphere is so vital that scientists believe life on land probably would not have evolved - and could not exist today - without it.
Thus, the correct answer is option C.
