Which refrigerant is a hydrofluorocarbon?

Explanation:
Hydrofluorocarbons are refrigerants made from carbon, hydrogen and fluorine (no chlorine). R-134a fits this group as 1,1,1,2-tetrafluoroethane, a commonly used HFC refrigerant. The other options aren’t HFCs: R-600A is a hydrocarbon, R-1234yf is a hydrofluoroolefin (an HFO, not an HFC), and R-12 is a chlorinated refrigerant (a CFC). This combination of elements and the absence of chlorine is what makes R-134a an HFC.
