The correct option is D Chlorofluorocarbon
The correct option will be chlorofluorocarbon.
- Among the given options, carbon dioxide, sulphur dioxide and nitrogen dioxide are responsible for air pollution and global warming.
- While chlorofluorocarbons (CFCs) and other halogenated ozone-depleting substances (ODS) are mainly responsible for ozone depletion.
- CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules as shown in the figure.
