An international organization formed after WWII to promote international peace, security, and cooperation.

• A. IMF
• B. NATO
• C. European Union
• D. United Nations

Answer: (D)

The main idea here is the founding purpose of the United Nations: after World War II, nations created it to promote international peace, security, and cooperation. It began in 1945 as a global forum to prevent another world conflict, provide a venue for diplomacy, coordinate humanitarian aid, and support development and human rights. Its structure, including the Security Council and General Assembly, is built around collective action to address global problems through dialogue and cooperation rather than force alone. The other options don’t fit as well: the International Monetary Fund focuses on global economic stability, not peace and security; NATO is a military alliance centered on collective defense; and the European Union is a regional bloc aimed at economic and political integration in Europe. The United Nations best matches the description of an organization formed after World War II to promote peace, security, and cooperation worldwide.
