Answer:
B. League of Nations.
Step-by-step explanation:
League of Nations (LON) was founded after World War I by the President of the United States of America, Pres. Woodrow Wilson on the 10th of January, 1920. It is the first official worldwide intergovernmental organization and it had its headquarters in Geneva, Switzerland.
The main mission or purpose of the League of Nations was to prevent global conflicts, maintain and enhance peace all over the world, as well as facilitate international cooperation among nations.
However, the League of Nations failed due to the lack of unanimity with respect to decision-making among countries.
Hence, League of Nations was the failed multinational body that was replaced by the United Nations.
