Which of the following is an HCFC refrigerant?

Explanation:
Identifying refrigerant families by their chemical makeup is what this tests. HCFCs (hydrochlorofluorocarbons) contain hydrogen, chlorine, and fluorine. Among common options, the one that fits this group is R22, known as HCFC-22. The other refrigerants are different families: R11 is a CFC (chlorofluorocarbon), while R134a and R410A are HFCs (hydrofluorocarbons) that do not contain chlorine. So R22 is the HCFC refrigerant.
