Final answer:
The statement that Wallace Hartley's violin was never recovered is not true. His violin was found in 2006 and sold at auction in 2013 for a large sum, making option D the incorrect statement regarding the facts about Hartley and his violin.
Step-by-step explanation:
The correct answer is D: His violin was never recovered.
This statement is not true because Wallace Hartley's violin was eventually recovered. Hartley was indeed the head of the Titanic band (A), and he did bring his violin with him on the Titanic (B). Tragically, Hartley died during the sinking of the Titanic (C). However, in 2006, the violin was found and, after extensive forensic testing, was confirmed to have belonged to him. It later sold at auction in 2013 for 1.7 million dollars.
