Explanation
Option B is undesirable because a refrigerant having vapor pressure below atmospheric pressure at the temperature of the refrigerator coils can cause issues such as air leakage into the system. In contrast, being non-explosive (A) and having high vapor pressure at condenser temperature (C) are generally favorable characteristics.
