Solution
The correct option is D Ozone
Ozone is a molecule made up of three oxygen atoms. The high concentration of ozone that is found in the stratosphere around 15 – 30km above the Earth's surface is called the ozone layer. Ultraviolet radiation from the sun is blocked by the ozone layer and thus it acts as a shield.
A Dobson unit (DU) is the unit of measurement of ozone in a column of air from the ground to the top of the atmosphere.
