Which of the following represents the letter K in the phonetic alphabet?

The letter K in the phonetic alphabet is represented by the term "Kilo." The phonetic alphabet, also known as the NATO alphabet, is established for clarity in communication, especially in military contexts, where misunderstandings can have critical consequences. Each letter is associated with a specific word to ensure distinct and recognizable communication over radio or telephone.

"Kilo" is the correct term because it is universally accepted within military and aviation communications to signify the letter K. This helps prevent confusion with similar-sounding letters or words. The other options like "Kite," "King," and "Kangaroo" may be intuitive guesses, but they do not hold the same standardized recognition or use in formal communication. Thus, "Kilo" is the appropriate choice for representing the letter K in the phonetic alphabet.
