A. Oxygen
B. Nitrogen oxide
C. Chlorofluorocarbons
D. sulphur dioxide
Correct Answer:
Option C – Chlorofluorocarbons
Explanation
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.
