Which halogen is used as a refrigerant?
Correct answer: A. F

Explanation
Fluorine (F) is used in the production of various refrigerants, particularly in the form of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). However, due to their negative impact on the ozone layer, the use of CFCs and HCFCs has been phased out in many countries.
