What is the phonetic word associated with the letter O?

The phonetic word associated with the letter O is Oscar. The NATO phonetic alphabet, which is used in aviation and other fields for clear communication over radio or in noisy environments, assigns a distinct word to each letter to prevent confusion. In this system, the letter O is represented by Oscar, ensuring that when spoken, it is clear and easily recognized, minimizing the chances of miscommunication.

The other options represent different letters in the phonetic alphabet: Golf corresponds to G, Juliett corresponds to J, and Kilo corresponds to K. Each of these words is specifically chosen to represent their respective letters clearly and distinctly, but they do not represent the letter O.
