Which of the following is a valid door width for an exit serving 10+ occupants?

• A. 30 inches
• B. 32 inches
• C. 28 inches
• D. 34 inches

Answer: (B)

The main idea is the minimum egress door width required for exits with a certain occupant load. For an exit serving 10 or more people, the door opening must provide a clear width of at least 32 inches. This ensures people can pass through safely in normal use and during an emergency. Among typical options, 32 inches meets that minimum and is the code-compliant width to ensure adequate egress. A narrower width would not comply, while a wider width (like 34 inches) is acceptable but goes beyond the minimum. So the 32-inch width is the correct, minimum standard to satisfy the requirement.
