Answer: S

The letter S is used in the message "SOS", which is one of the most common and well-known uses of the Morse code. The letter O is made with three dashes. Although SOS is often said to stand for "Save Our Ship" or "Save Our Souls", it actually doesn't stand for anything.

When Morse code was first invented, it was one of the only ways to send electronic messages. It was also used in wars as a message system.
