Explanation:
In the radio alphabet used for clear voice spelling, each letter has a distinct code word. E, M, and S are spoken as Echo, Mike, and Sierra. That exact trio—Echo, Mike, Sierra—matches the letters E, M, and S, so it’s the correct set. The other options mix in incorrect words: Sierrae isn’t a standard code word, Alpha corresponds to A, and November corresponds to N, not M. Using Echo, Mike, and Sierra ensures your letters are understood clearly, especially on noisy maritime channels.
