Which refrigerant is also known as CFC-12?

The concept here is naming conventions for refrigerants and the idea that older common names map to the modern designations. CFC-12 is the same chemical as R-12—the “R-” code is the refrigerant’s industry designation, while “CFC-12” is the historic common name for the same compound (dichlorodifluoromethane). So the refrigerant also known as CFC-12 is R-12. The other options refer to different substances: R-134a is a non-CFC refrigerant (HFC-134a), and R-290 is propane, a hydrocarbon refrigerant.
