The presence of ozone in the stratosphere is responsible for

A Increasing the average global temperature in recent years
B Higher rate of photosynthesis<br>
C Checking the penetration of ultraviolet rays to the earth
D Supplying oxygen for people travelling in jets

Correct Answer: Checking the penetration of ultraviolet rays to the earth

Ozone in the stratosphere protects us from the Sun's harmful ultraviolet rays. However, ozone in the troposphere, closer to Earth's surface, is a pollutant and hazardous to our health.
