(B) \(CO_2\)

(C) Freon

(D) All of these

Answer 1

Correct option is: (C) Freon

Freons are a class of compounds that are primarily used as refrigerants and aerosol propellants. They are known for their stability and non-flammable nature.

The most common Freons that are known to cause damage to the ozone layer are \(CFCl_3\) (Trichlorofluoromethane) and \(CF_2Cl_3\) (Dichlorodifluoromethane). These compounds are halogenated hydrocarbons.
