The phonetic alphabet letter O is represented by which word?

The phonetic alphabet letter O is represented by the word "Oscar." The NATO phonetic alphabet, also known as the International Radiotelephony Spelling Alphabet, was developed to ensure clarity and prevent miscommunication, especially over radio or telephone communications where similar-sounding letters might be confused. Each letter is assigned a unique, easily recognizable word.

"Oscar" was chosen because it is distinctive and less likely to be misunderstood in various spoken contexts, making it effective for communication. This system is widely used in military, aviation, and emergency services to convey letters clearly. The other options, while they do start with the letter O, are not part of the NATO phonetic alphabet and therefore do not serve the intended purpose of enhancing clarity in communication.
