Which of the following is responsible for the depletion of ozone layer in the upper atmosphere?

The correct option is C Chlorofluorocarbons

• The ozone layer acts as a filter for UV-radiation from the sun. therefore, this process serves as a protective shield to human life against the adverse effects of UV like burn and some skin cancer. It is obvious that any depletion of stratospheric ozone would be harmful to life on this earth.
• Primary reason for ozone layer depletion is CFC (chloro fluoro carbon) or freon.
