A key-operated lock can be a built-in lock or a padlock.

• A. Sometimes
• B. True
• C. Not applicable
• D. False

Answer: (B)

Key-operated locks come in multiple forms, all defined by needing a key to operate the mechanism. This includes built-in locks, which are installed inside doors, furniture, or safes, as well as padlocks, which are portable with a locking hasp and shackle. Because both of these form factors can be operated with a key, the statement is true. The other options don’t fit because this describes a general capability of key-operated locks, not something that’s only sometimes or never true.
