Which of the following are examples of the NATO Phonetic Alphabet?

The standard phonetic alphabet used in amateur radio, aviation, and maritime communications worldwide is the ITU/NATO Phonetic Alphabet. This standardized system ensures that letters are clearly understood over noisy or weak radio signals, minimizing confusion between similar-sounding letters like B, C, D, and E. The correct sequence for the first four letters of the alphabet in this system is Alpha, Bravo, Charlie, and Delta. The other options feature obsolete or localized phonetic systems. For example, 'Able, Baker, Charlie, Dog' is from an older World War II-era phonetic alphabet, and 'Adam, Boy, Charles, David' is often used by local law enforcement but is not the international standard for amateur radio.
