What is a plenum?

• A. An enclosed space inside a building used for airflow.
• B. A device for detecting gas leaks.
• C. A type of fire extinguisher.
• D. A closed storage chamber for electrical components.

Answer: (A)

A plenum is an enclosed space inside a building used for airflow in the HVAC system. It serves as the air-handling chamber where air is collected or distributed, often located above ceilings or below floors. This makes it the correct description because it specifically refers to a space designed for moving and housing air. It’s not a device for detecting gas leaks, a fire extinguisher, or a closed storage chamber for electrical components, which are different things with other purposes.
