- ✓ Compressor, condenser, metering device, and evaporatorCorrect
- B. Compressor, receiver, filter-drier, and evaporator
- C. Condenser, receiver, expansion valve, and cooling coil
- D. Compressor, condenser, receiver, and evaporator
Why A is correct
NAVEDTRA 14075 §6-1 identifies exactly four essential components connected in a loop: the compressor, the condenser, the metering (expansion) device, and the evaporator. The receiver and filter-drier are ancillary components, not part of the four-component loop.
