What statement is true concerning a liquid desiccant cargo-hold dehumidification system?

AWater vapor from the humid air inlet from the cargo hold is condensed and absorbed into the liquid desiccant by means of a heating coil located in the humidification chamber.

BWater from the humid air inlet from the cargo hold is evaporated and driven out of the liquid desiccant by means of a cooling coil located in the humidification chamber.

CWater vapor from the humid air inlet from the cargo hold is condensed and absorbed into the liquid desiccant by means of a cooling coil located in the humidification chamber.

DWater from the humid air inlet from the cargo hold is evaporated and driven out of the liquid desiccant by means of a heating coil located in the humidification chamber.

AI Explanation

The correct answer is C. In a liquid desiccant cargo-hold dehumidification system, water vapor from the humid air inlet of the cargo hold is condensed and absorbed into the liquid desiccant by means of a cooling coil located in the humidification chamber. This is because the cooling coil helps to lower the temperature of the air, causing water vapor to condense and be absorbed by the liquid desiccant. The other options are incorrect because they describe the opposite process, where water is either evaporated from the liquid desiccant or absorbed into it using a heating coil, which is not how a liquid desiccant cargo-hold dehumidification system typically operates.
