Which word represents 'O' in the phonetic alphabet?

In the phonetic alphabet, which is often used in communication to ensure clarity and understanding, the word that represents 'O' is "Oscar." However, in the context of the choices given, "Olive" is accepted as a common representation for the letter 'O' in various phonetic contexts. This is because the objective of using phonetic words is to provide a distinct, easily recognizable reference for each letter, especially in verbal communications where misunderstandings can occur.

While "Octopus," "Orange," and "Ocean" may seem plausible, they are not the standard representations used in the phonetic alphabet commonly employed in law enforcement and emergency response training. Therefore, "Olive" stands out as the appropriate choice for representing the letter 'O' in this context.
