The Correct Answer:- Ozone gas

Ozone gas is a gas shield above the surface of the earth that protects us from harmful radiation from the sun.

• Ozone gas is regarded as a highly reactive gas.
• Ozone gas is composed of three molecules of oxygen.
• The Ozone layer is present in the Stratosphere and around 9 to 18 miles (15-30 km) above the earth.
