Answer:
B) the establishment of the League of Nations
Step-by-step explanation:
The League of Nations was an international body created by the Treaty of Versailles, in 1919 after the end of the First World War. It was dissolved in 1946. Although President Woodrow Wilson was hoping to participate in peace, there was a refusal to enter by the Americans, which led to the disengagement of European political affairs, harmful to world stability.
