To acknowledge receipt of a message, which code is appropriate?

• A. Acknowledgement
• B. Stop Transmitting
• C. Reply
• D. In Service

Answer: (A)

Acknowledging receipt of a message is the act of confirming that you heard and understood what was sent. The best code for this is the one that names the action itself—Acknowledgement. Using this code lets the sender know the transmission arrived and doesn’t add content or instructions, keeping the communication clear and efficient. It’s different from stopping transmissions, which is a control command to halt radio use; a reply would convey new information or instructions rather than simply confirming receipt; and In Service is a status update about availability, not about confirming a specific message was received. In practice, you’d send an acknowledgment promptly to close the loop and ensure both sides are aligned.
