Answer:

The correct answer is A) ozone

Explanation:

Ozone(O₃) is a layer made up of 3 oxygen molecules and present in the stratosphere layer of atmosphere. The ozone layer absorbs most of Sun's ultraviolet rays and protect us from UV radiation. These ultraviolet light are harmful to animals and humans and can cause skin cancer.

In the stratosphere, ozone is continuously converted into molecular oxygen by UV radiation which breaks O₃ into O₂ and O. Then again this O₂ converts into O₃ so the process is interchangeable.

The radiation blocked by ozone cause the heating of the stratosphere so ozone plays important role in maintaining the temperature of the earth's atmosphere.
