Answer 1

The correct option is C

Dobson units are not used to measure ozone content.

The thickness of the ozone is measured in terms of Dobson Units (DU). In the stratosphere, ozone gas is continuously formed by the action of ultraviolet rays on molecular oxygen and also degraded into molecular oxygen.
