Which international organization formed in 1920 to promote cooperation and peace among nations?

• A. United Nations
• B. League of Nations
• C. NATO
• D. World Health Organization

Answer: (B)

After World War I, there was a strong push to find a formal way for nations to work together to prevent future wars and settle disputes peacefully. The organization formed in 1920 to carry that idea forward was created to promote cooperation among countries and respond collectively to aggression, aiming to maintain peace through diplomacy and sanctions if needed. This represents an early effort at international cooperation that tried to replace conquest with consultation and joint action.

Other options were established later and for different purposes: the United Nations was created after World War II to build a broader framework for international security and development; NATO emerged in 1949 as a military alliance for collective defense; and the World Health Organization began in 1948 to focus on global health.
