Which is an HFC refrigerant?

HFC refrigerants are hydrocarbons that contain hydrogen, carbon, and fluorine but do not contain chlorine. R-134a fits this pattern, being 1,1,1,2-tetrafluoroethane, which has fluorine and hydrogen without any chlorine. The other options include chlorine (R-12 and R-22 are CFC/HCFC with chlorine) or are hydrocarbons (R-600A is isobutane, a hydrocarbon) and thus are not HFCs.
