Which side is the condenser a part of?

A Heating Ventilating Air Conditioning System, known as HVAC, uses a condenser to precipitate steam vapors into a liquid. As shown in the picture above, steam enters the top of the vessel, passes over and around the coil piping.

The liquid contained in the coil absorbs the heat from the steam. This process causes the steam to condense which changes it to water or droplets called condensate. In this diagram, the coil is located in the center of the unit. so D. none of the above would be the answer.
