Solution
The correct option is A Depletion of the ozone layer
Chlorofluorocarbons (CFC) also known as freons which cause a destruction of ozone layer found in the stratospheric layer. The ozone layer in the atmosphere prevents the harmful UV rays from reaching the earth surface. When this ozone layer gets depleted, harmful UV rays causes skin cancer.
