Final answer:
Option (4), Woodrow Wilson was the US President during World War I, leading the United States into the conflict in 1917 and later presenting the Fourteen Points for peace.
Step-by-step explanation:
The US President during World War I was Woodrow Wilson. The conflict, known as "the Great War," saw the United States entering in 1917 under Wilson's leadership. Despite initially adopting a stance of neutrality and a focus on domestic reform, Wilson was compelled to join the Allies due to repeated German aggressions and the need to protect the rights of neutral nations.
Wilson's role in the war and his subsequent efforts to shape the postwar world, including his presentation of the Fourteen Points, were significant in the history of American foreign policy.
