Which of the following could illustrate a restricted area?

• A. A roped off area, a specially designated cubicle, or an office with a closed door.
• B. An open cubicle with no door.
• C. A public hallway.
• D. A storage closet in a shared hallway.

Answer: (A)

Restricted areas are defined by visible barriers and controlled access. A roped-off area shows a physical boundary that signals entry is not free for everyone, a specially designated cubicle marks a space reserved for people with authorization, and an office with a closed door indicates that entry can be restricted or require credentials. These features collectively convey that access is limited to authorized individuals, which is what a restricted area is all about.

The other options lack clear barriers or access controls: an open cubicle with no door invites entry, a public hallway is openly accessible, and a storage closet in a shared hallway doesn’t show clear, enforceable access restrictions.
