Which of the processes listed would be the most satisfactory method to use to lower the humidity of the air being circulated by an air conditioning system?

Correct Answer: Option B — Cooling the air to a point below dew point, and then reheating it.

Dehumidification in marine HVAC requires chilling the air below its dew point to condense out moisture, followed by reheating to maintain comfortable dry-bulb temperatures within the conditioned space.
