Correct Answer:
B. 1945
The United Nations (UN) is a crucial international organization established to promote international cooperation and maintain global peace and security. It was officially founded in 1945. Specifically, the UN Charter was signed on June 26, 1945, and came into force on October 24, 1945, following its ratification by the five permanent members of the Security Council (China, France, the Soviet Union, the United Kingdom, and the United States) and a majority of other signatories. The UN was created in the aftermath of World War II to prevent future global conflicts.
- While preliminary discussions and planning for the UN, such as the Dumbarton Oaks Conference, occurred in 1944, the organization was not officially founded that year.
- By 1946 and 1947, the United Nations was already established and actively engaged in its initial operations, having been founded the previous year.
