A) A german U-boat sank a British merchant ship, the Lusitania, killing 124 Americans

But the real reason was, not only the sinking of Lusitania, but the Zimmermann Telegram, in which Germany would help Mexico take back all their lands lost back in the Mexican-American war if Mexico joined the war effort on the Central Power side
