Which word represents the letter 'R' in the NATO phonetic alphabet?

The NATO phonetic alphabet was developed to provide clarity in communication, particularly in situations where misinterpretation could occur, such as radio transmissions. In this alphabet, each letter of the English language is assigned a specific word to represent it. The letter 'R' is represented by the word "Romeo." This term was chosen for its distinct sound, which helps ensure accurate recognition and avoids confusion with other letters that might sound similar.

The other options—River, Radar, and Rush—are not part of the official NATO phonetic alphabet. They do not serve the same purpose of representing the letter 'R' in a standardized way, which could lead to miscommunication, especially in critical situations like military or emergency communications. Using "Romeo" helps maintain clarity and consistency across different languages and accents.
