Concerning cargo-hold dehumidification, what statement is true?

Correct Answer: Option A — Cargo-hold moisture content is reduced by supplying relatively dry air from the outside and exhausting relatively humid air to the outside.

Cargo-hold dehumidification relies on replacing humid hold air with drier outside air. By exhausting the moisture-laden air and introducing air with a lower dew point, the overall moisture content within the hold is reduced, preventing condensation and cargo damage caused by sweating or high humidity levels during transit.
