Which code indicates Temporarily busy?

• A. Be on the lookout
• B. Temporarily busy
• C. In service / Available
• D. Acknowledgement

Answer: (B)

In radio communications, units signal their current capacity to take new assignments with short status codes. When you’re momentarily tied up with an ongoing task and can’t take a new call right away, you use the code that explicitly indicates you’re not available but will be soon. That exact label—Temporarily busy—communicates this state clearly to dispatch and other units, so they know not to assign you additional tasks until you’re free again. It’s the best choice because it directly and unambiguously conveys your temporary unavailability.

For comparison, interpreting the other options: Be on the lookout is a broadcast instruction to monitor for a person or object (a search notice), not a status of your own availability; In service / Available means you’re free to take calls; Acknowledgement is simply confirming you received a message.
