D the death of the heir to the Italian throne

Answer 1

The correct response is B: the sinking of the Lusitania. The Lusitania, a British ocean liner, was sunk by a German U-boat in 1915, which resulted in the deaths of many American passengers and contributed to growing anti-German sentiment in the United States, ultimately leading to the U.S. entry into World War I in 1917.
