B Correct answer
Explanation

Freon (chlorofluorocarbon or CFC) was the most widely used refrigerant in domestic refrigerators and cold storage facilities for decades due to its excellent thermodynamic properties. Neon is a noble gas used in lighting, while crypton (likely a misspelling of krypton) is another noble gas. Freon has been largely phased out due to ozone depletion concerns, but it was the standard refrigerant when this question was framed.
