Alkylbenzene (AB) oil is miscible in HCFC refrigerants.

Explanation:
Alkylbenzene oil is a hydrocarbon lubricant designed to be miscible with halogenated refrigerants that contain chlorine, such as HCFCs. Because of this compatibility, the oil mixes with the HCFC refrigerant rather than staying as a separate phase, which helps the lubricant circulate with the refrigerant to the compressor. This is why AB oil is commonly used with HCFC refrigerants like R-22. The statement is true since AB oil’s miscibility is specific to HCFC refrigerants, not generally to CFCs or many HFCs.
