Solution

The correct option is A Chlorofluorocarbons
Chlorofluorocarbons(CFCs) are the harmful gases which react with ozone in the atmosphere and releases oxygen gas( $O_{2}$ ) and atomic oxygen (O). This leads to the creation of ozone hole, which is harmful to life on earth as UV rays will reach the earth's surface. Whereas other given gases (nitrogen, $C O_{2}$ , $S O_{2}$ ) will not lead to ozone layer depletion.
