B. Low-loss fittings are required since January 1992
C. There is no reason not to trap liquid refrigerant in the hose since it will avoid venting of refrigerant

The correct answer to this question is A, and There is no pressure relief valve on the standard hose and the liquid refrigerant trapped in the tube could build up significant pressure and rupture the tube. Refrigerants are fluids that are used in refrigeration cycles and heat pumps.

In these cycles, the fluid is usually turned from liquid to gas and then back again. Examples of these fluids that have been used include chlorofluorocarbons and fluorocarbons. Though the use of these types of liquids has decreased due to their environmental hazards, it is essential to transfer these liquids properly, so it doesn't cause harm to the machine.
