Step-by-step explanation:
The correct answer to the question is C. Filter drier. A filter drier is usually installed between the liquid line or condenser and the capillary tube in order to help prevent contaminants from entering the capillary tube.
It acts as a filter, removing any impurities or moisture from the refrigerant before it reaches the capillary tube.
Evaporator is the component of an air conditioner that converts liquid refrigerant into gas, while condenser is the component that converts gas into liquid. The compressor is responsible for compressing the refrigerant gas.
