What vent is specifically used to exhaust air and moisture from a clothes dryer?

The correct answer is the dryer vent because it is specifically designed for the unique requirements of a clothes dryer. A dryer vent is intended to safely exhaust air and moisture generated during the drying process, carrying away lint, hot air, and excess humidity from the dryer to the outside of the building.

The design of a dryer vent includes features that prevent lint build-up, which can be a fire hazard, and ensure that the expulsion of warm, moist air is efficient and effective. Proper installation and maintenance of the dryer vent are essential for not only the appliance's efficiency but also for reducing the risk of fires related to lint accumulation.

While options like venting duct and exhaust vent can refer to similar systems for other appliances or general air movement, they do not specifically denote the venting system meant for clothes dryers. An air outlet vent typically refers to ventilation systems not specific to laundry appliances. Hence, it is the dryer vent that clearly defines the application for clothes dryers, making it the best choice in this context.
