Which phonetic alphabet code corresponds to the letter S?

The phonetic alphabet, often called the NATO phonetic alphabet, is used to ensure clarity and avoid miscommunication when spelling out words over radio or telephone communication. Each letter of the alphabet is represented by a specific code word to minimize confusion, particularly in high-stakes environments like military or emergency services.

The code word that corresponds to the letter S is "Sierra." This term is widely recognized and used internationally to represent the letter S, making it effective for communication in a variety of situations where clarity is critical. Each code word is uniquely associated with its respective letter, and "Sierra" serves this purpose for S with no potential for misunderstanding.

The other code words mentioned in the choices correspond to different letters: "Victor" represents the letter V, "Whiskey" is used for W, and "X-ray" stands for X. Each of these is distinct from "Sierra," highlighting the importance of using the correct term to ensure accurate communication.
