B Correct answer
Explanation

Freon is the correct answer. It's a trade name for chlorofluorocarbon (CFC) refrigerants that were commonly used in refrigerators and air conditioning systems. Neon is used in lighting, crypton is not a real chemical (likely a distractor), argon is an inert gas used in welding and lighting, and ice is not a refrigerant but rather a cooling medium.
