Which word is associated with the letter X in the phonetic alphabet?

In the phonetic alphabet, the letter "X" is represented by the word "X-ray." This system, known as the International Radiotelephony Spelling Alphabet or NATO phonetic alphabet, is used to ensure clarity and reduce misunderstandings when communicating letters over radio or telephone communications, particularly in noisy environments or situations where miscommunication could be critical.

The word "X-ray" is specific to the letter "X" and serves an essential role in a variety of contexts, including emergency services, military, aviation, and any situation where clear communication is paramount. Recognizing "X" as "X-ray" helps operators accurately convey important information without confusion. In contrast, the other words in the options—Tango, Victor, and Oscar—represent different letters in the phonetic alphabet: "T" for Tango, "V" for Victor, and "O" for Oscar, which do not correspond with the letter "X."
