Which phonetic alphabet letter is denoted by 'Z'?

The letter 'Z' in the phonetic alphabet is represented by the word 'Zulu.' This terminology is used internationally for clear communication, especially in military and aviation contexts, to avoid misunderstandings that can arise from similar-sounding letters. By using 'Zulu' to denote 'Z,' it ensures that the letter is easily recognizable and distinguishable under various conditions, contributing to effective and reliable communication.

Other options such as 'Zenith,' 'Zebra,' and 'Zodiac' are not officially recognized terms in the phonetic alphabet used by the military and aviation sectors. While they may represent words that begin with 'Z,' they do not serve the purpose of standardized communication, which is the primary function of the phonetic alphabet.
