A
Correct answer
Explanation
The RMS Titanic was one of the first ships to use the SOS distress signal when it sank in 1912. While SOS was adopted as the international standard in 1906, the Titanic's distress call made it famous. The other options - 'Typooon' and 'Columbisis' - appear to be misspelled or fictional. Royal Navy is not a ship name.
