Solution
The correct option is B UV rays The ozone layer in the stratosphere of the atmosphere filters the rays of UV that come on the surface of the earth. CFCs are the primary cause of ozone layer depletion, which allows UV rays to enter the earth's atmosphere. UV rays cause harmful effects on both plants and animals such as cancers, cataracts, and immune deficiency disorders.
