Ground level ozone reflects and absorbs harmful UV rays from the sun.

• A. True
• B. Not applicable
• C. Both true and false
• D. False

Answer: (D)

The protective effect against UV comes mainly from the ozone layer high in the atmosphere, not from ozone near the ground. Stratospheric ozone absorbs most of the sun’s harmful ultraviolet radiation, especially UV-B and UV-C, reducing what reaches the surface. Ground-level ozone is a harmful pollutant formed from reactions of pollutants like NOx and VOCs in sunlight; it is not a reliable shield against UV and can actually worsen health and air quality. While ozone can absorb some UV, the amount present at ground level isn’t enough to provide meaningful protection, and the idea of reflecting UV isn’t how ozone works. So the statement is false.
