Who was the President during World War I?

The correct answer is Woodrow Wilson because he served as the President of the United States from 1913 to 1921, a period that includes the entirety of World War I, which lasted from 1914 to 1918. Wilson played a significant role in the U.S. involvement in the war, advocating for important policies such as the draft and war financing, as well as promoting his vision for a post-war world that included the establishment of the League of Nations, aimed at ensuring long-term peace.

In contrast, Franklin D. Roosevelt served as President during World War II, which occurred from 1939 to 1945. Theodore Roosevelt was President from 1901 to 1909, prior to World War I. Herbert Hoover was in office from 1929 to 1933, after World War I had concluded. Thus, Wilson is the only figure among the choices provided who was in the presidential office during the time of World War I.
