The most accurate response to how World War I contributed to the events leading up to World War II is:
Germans hated the Versailles treaty and supported Hitler's actions to defy it.
The Treaty of Versailles, which ended World War I, imposed harsh penalties and reparations on Germany, leading to widespread resentment among the German population. This resentment was a significant factor in the rise of Adolf Hitler and the Nazi Party, who capitalized on these feelings by promising to overturn the treaty and restore Germany's former glory, ultimately leading to the outbreak of World War II.
