Final answer:
No, the statement is False. Only one of the four remaining officers of the Titanic eventually became a captain.
Step-by-step explanation:
No, the statement is False.
After the Titanic disaster, the surviving officers were not all promoted to captain. In fact, only one of the four remaining officers, Second Officer Charles Lightoller, eventually became a captain.
Despite his experience and involvement in the Titanic disaster, Lightoller was not promoted to captain until 1918, after serving as a crew member in the Royal Navy during World War I.
