Answer: The correct answer is "It has increased surface levels of ultraviolet light".
Explanation:
Ozone depletion: The ozone layer in the atmosphere protects the earth's surface from the exposure of the harmful radiation but due to the hole in the ozone layer, the harmful radiation is reaching our earth's surface.
The ultraviolet radiation is very harmful radiation. It can cause skin cancer and eye cataract.
When the ozone layer is hit by the ultraviolet radiation then ozone will break into oxygen molecule and oxygen atom. Oxygen atom is unstable then it will react with another oxygen molecule. In this way, the ozone layer is not damaged.
CFC (chloro fluoro carbon) is the pollutant which are responsible for the ozone depletion. Due to the depletion of the ozone layer, the surface levels of ultraviolet light has increased.
