The correct answer is D) high-pressure liquid. In a typical refrigeration system, the refrigerant leaves the receiver in a high-pressure liquid state. This is because the receiver is located after the condenser, where the refrigerant has been compressed and cooled, resulting in a high-pressure liquid condition. The high pressure is maintained to ensure the refrigerant can effectively flow through the expansion valve and into the evaporator, where it will undergo a phase change to a low-pressure vapor. The other options are incorrect because the refrigerant would not be in a low-pressure state (either vapor or liquid) as it leaves the receiver, and it would not be in a vapor state at this point in the refrigeration cycle.
