Which category lists Single Cylinder and Deadbolt?

• A. Locks
• B. Doors
• C. Windows
• D. Lights

Answer: (A)

Single Cylinder and Deadbolt describe locking hardware used on doors. They define how a door is secured, not the door itself or the opening. A single cylinder lock typically has a key on the outside and a thumbturn on the inside, while a deadbolt is a strong locking mechanism that extends a solid bolt into the frame and is operated by a key or thumbturn. Both are types of locks, which is why the correct category is Locks. Doors are the openings the locks secure, windows are separate openings, and lights are unrelated hardware.
