A
Chlorofluorocarbons
💡 Explanation:
$ { CFC } _{ s } $ are widely used as refrigerants. $ { CFC } _{ s } $
discharged in the lower part of atmosphere move upward and reach
stratosphere. In stratosphere, UV rays act on them releasing CI atoms.
CI degrades ozone releasing molecular oxygen, with these atoms acting
merely as catalysts; CI atoms are not consumed in the reaction. $ { CFC
} _{ s } $ added to the stratosphere have permanent and continuing
affects on ozone levels.
So, the correct answer is 'Chlorofluorocarbons'.
