Which code word is used for the letter X?

• A. Xylophone
• B. X-ray
• C. Xenon
• D. Xeno

Answer: (B)

In radiotelephony, each letter has a distinct code word to keep messages clear. For the letter X, the standard code word is X-ray. It’s chosen because it’s a common, easy-to-pronounce word that begins with X and has phonetic sounds that are unlikely to be confused with other letters when spoken over a radio, which helps prevent miscommunication in busy or noisy environments. The other options—while familiar words starting with X—are not part of the official spelling alphabet, so they aren’t used in formal communications.
