Which phonetic alphabet letter is represented by "kilo"?

The phonetic alphabet letter represented by "kilo" is indeed "K." The phonetic alphabet, often used in military and aviation contexts, assigns specific words to letters in order to avoid confusion, especially when spelling out words over radio or telephone communications.

Each letter corresponds to a unique word that is easily distinguishable from others, reducing the risk of miscommunication. In this case, "kilo" is the word used for the letter "K." Each of the other options corresponds to different letters, and doesn't relate to "kilo." This system is important for clarity in communication, particularly under noisy conditions or when the spelling of names and terms is critical.
