• D. CLARITY

Answer: (C)

The ABCs in radio communication are Accuracy, Brevity, and Clarity. Accuracy means conveying the right information—correct call signs, frequencies, times, and instructions. A small error can lead to wrong actions, so verify details and spell out numbers or identifiers when there’s any chance of mishearing. Brevity is about keeping messages concise and to the point, using standard phrases and avoiding unnecessary words. This saves airtime and reduces the chance of confusion. Clarity focuses on how the message is delivered—speak clearly, at a steady pace, pronounce numbers and letters distinctly, and avoid slang or vague terms so the listener can understand it on the first pass. When you combine these three, you get messages that are correct, efficient, and easy to understand, which is essential for safe and effective radio communication.
