Final answer:
The RMS Olympic, Titanic's sister ship, had a successful 24-year career as a passenger liner, also serving as a troop transport during WWI and earning the nickname 'Old Reliable'.
Step-by-step explanation:
The Titanic indeed had a brief life, coming to an infamous end on her maiden voyage in 1912. However, her sister ship, the RMS Olympic, had a different fate. Option A would be the correct choice here. The RMS Olympic had a long and illustrious career as a passenger liner. Not to be confused with the RMS Lusitania, which was a different British ocean liner that tragically sank after being hit by a German submarine in 1915. Whereas the Titanic fell prey to an iceberg on her first outing, the Olympic served for 24 years, and even served in World War I as a troop transport, earning a nickname as 'Old Reliable' for her longevity.
