What is the phonetic alphabet code for the letter O?

The phonetic alphabet code for the letter O is indeed represented by "Oscar." This term is part of the NATO phonetic alphabet, which is used to clearly communicate letters over radio or telephone, particularly in situations where clarity is essential. Each letter of the alphabet is associated with a specific word to avoid confusion that might happen with similar-sounding letters. In this case, "Oscar" corresponds specifically to the letter O, making it the correct choice in this context.

The other terms mentioned, like "Foxtrot," "India," and "Lima," correspond to the letters F, I, and L, respectively. Thus, they do not represent the letter O, highlighting how crucial it is to correctly associate each phonetic term with its corresponding letter when communicating effectively.
