Solution

The correct option is D
Ozone

Ozone at the higher levels of the atmosphere is a product of UV radiation acting on oxygen (O2) molecule. The higher energy UV radiations split apart some moleculer oxygen (O2) into free oxygen (O)atoms. These atoms then combine with the molecular oxygen to form ozone as shown--

$O_{2}$ $U V - - \to$ O+O

O+ $O_{2}$ $\to$ $O_{3}$ (Ozone)
