Which code means Acknowledgement?

Which code means Acknowledgement?

• A. 10-8 In service
• B. 10-1 Receiving poorly
• C. 10-2 Receiving well
• D. 10-4 Acknowledgement

Answer: (D)

In radio communication, certain codes are used to keep messages concise and unambiguous. The code that means Acknowledgement is the one reserved for confirming that a message was received and understood. Using it closes the loop on a transmission, letting the sender know you’ve got and read the information. This is the best fit because it explicitly signals receipt and comprehension, which is the purpose of an acknowledgement. The other options describe different statuses: one indicates you’re on duty or in service, and the others refer to the quality of the radio signal (receiving poorly or receiving well). They don’t convey that a message was received, so they don’t serve the purpose of an acknowledgement.
