B Correct answer
Explanation

CFCs (Chlorofluorocarbons) were widely used in aerosol sprays, refrigerators, and air conditioning systems as refrigerants and propellants. However, they were never used in fire extinguishers - fire extinguishers use different agents like carbon dioxide, dry chemicals, foam, or halons (which are related but distinct from CFCs and were also phased out for environmental reasons).
