What does 'X' represent in the phonetic alphabet?

In the phonetic alphabet, 'X' represents "X-Ray." This term is widely recognized in various fields, such as aviation, military communication, and emergency services, as a way to convey clarity and prevent misunderstandings when spelling words aloud. The use of "X-Ray" helps ensure that the letter 'X' is easily understood, especially in high-stakes situations where miscommunication can lead to critical errors.

The other terms listed do not serve this specific purpose in standard communication protocols. "Xenon," while a recognized term in science, does not hold any relevance in the phonetic alphabet. "Xylo" and "Xander" are not established phonetic representations, making them unsuitable for this context. Thus, "X-Ray" is the standard and correct term used to represent 'X' in the phonetic alphabet.
