An air conditioner cools a room using a cooling cycle that is fundamentally most similar to which other common household appliance?

AA refrigerator
BA vacuum cleaner
CA toaster
DA washing machine

Explanation

An air conditioner cools indoor air using essentially the same fundamental refrigeration cycle as a household refrigerator, circulating a refrigerant that absorbs heat from indoor air and releases it outside the building. Warm indoor air is blown across coils containing the cold refrigerant, cooling the air before it’s circulated back into the room, while the absorbed heat is expelled outdoors through a separate set of coils. This shared underlying principle is why both appliances rely on a compressor to keep the refrigerant cycling continuously through the system.
