Which term means a space enclosed by walls and ceiling?

• A. Grade Plane
• B. Dwelling Unit
• C. Design Discharge
• D. Compartment

Answer: (D)

A space enclosed by walls and a ceiling is a compartment. This term is used to describe a discrete section of a building whose boundaries help contain fire and smoke, making it easier to limit spread and to plan sprinkler coverage within that boundary. The other terms don’t describe a physical enclosure: grade plane refers to the ground level relative to the building, a dwelling unit is the residential living area as a whole, and design discharge is about the expected water flow from sprinklers rather than a defined space. So the concept that fits the description is compartment.
