Which code is used to cancel the last message or assignment?

• A. 10-22
• B. 10-25
• C. 10-32
• D. 10-33

Answer: (A)

In radio communications, there is a code that signals to cancel a prior instruction or message. This particular signal is used when you want everyone to disregard the last transmission and stop acting on it, preventing follow-up actions based on outdated info. That matches what the question is asking for: the code whose purpose is to cancel the last message or assignment. So the option that conveys cancellation is the correct one. The other options point to different actions—arranging to meet with someone, referring to weapons, or signaling emergency traffic—so they don’t fit the request to cancel the previous instruction.
