The correct answer is: A. The League of Nations.
Explanation:
President Woodrow Wilson wrote 14 points to insure world peace after World War I. His first 5 points eliminated the main causes that led to war, the following points refered to restore territories and set boundaries. And his 14th point was the creation of a global organization to prevent wars and protect countries, named The League of Nations.
This fourteenth point was included in the Treaty of Versailles but the United States did not entered The League of Nations, because most Americans believed that this organization could lead to another war.
