The gas more destructive to ozone layer is?

Solution (By Examveda Team)

Of these gases, CFC, i.e., chlorofluorocarbons, cause major destruction to the ozone layer, which shields the earth from harmful ultra-violet radiation.
The most common sources of CFCs are refrigerants used in AC and refrigerators, while aircraft halon and aerosol sprays also emit CFCs into the atmosphere.
