Answer:
Option C, the US never joined the League of Nations, is the right answer.
Step-by-step explanation:
Following the end of the First World War, President Woodrow Wilson made a recommendation that attempted to preserve peace and avoid another war. To seal the balance of peace among Europeans, Wilson produced a document called Wilson's "14 points.
Though Europe followed the league it did not admit the enforcement of a peace treaty on the basis of the 14 points and thus launched the Treaty of Versailles.
The Congress of the United States yearning for the war effort and disenchanted by the "disloyalty" of its allies, determined for the non-integration of the U.S. into the League of Nations.
