Solution

The correct option is A Ozone
Ozone is a light bluish gas found in the upper layer of the atmosphere (stratosphere). It is found at about 16 km height from the earth’s surface. It prevents ultraviolet rays coming from the sun to reach the earth. Thus, it protects us from the harmful UV rays of the sun.
