The damage to ozone layer is caused by

A.

Oxygen

B.

Nitrogen oxide

C.

Chlorofluorocarbons

D.

sulphur dioxide

Correct answer is C

Ozone sits in the upper atmosphere and absorbs ultraviolet radiaton, another type of solar energy that's harmful to humans, animals, and plants. CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity

Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
