Correctional officers cannot carry firearms while on duty inside a correctional facility unless there is an emergency and command has approved the issuance of firearms. Which option completes the sentence?

• A. Cannot
• B. Can
• C. Must
• D. Should

Answer: (A)

Inside a correctional facility, the norm is that firearms are not allowed for officers on duty. The sentence sets a strict rule with a specific, limited exception: only in an emergency and with command approval may firearms be issued. That makes the best completion the word that expresses a prohibition in general, with the emergency exception providing the narrow allowance. Using can would undo the general ban by implying permission to carry, while must or should would shift the statement into obligation or advisability rather than a clear prohibition with a defined exception. The chosen option cleanly communicates a safety-focused policy that prioritizes control and only allows firearms under clearly authorized emergency circumstances.
