A. Ozone gas has been used
B. Chlorofluorocarbons have been used
C. Carbon dioxide has been used
D. Hydrofluorocarbons have been used

Answer (2)

Chlorofluorocarbons (CFCs) were historically used in foamed plastics, propellants, and refrigerants, but their use has declined due to environmental concerns. Hydrofluorocarbons (HFCs) and carbon dioxide are now more commonly used alternatives. Ozone gas is not utilized in these applications.
