Which International Organisation came into existence immediately after World War-I?

League of Nations

The correct answer is Option (2) → League of Nations

The League of Nations was established in 1920 as part of the Treaty of Versailles, which ended World War I. Its primary purpose was to promote peace and cooperation among countries to prevent future conflicts. The League, however, faced various challenges and ultimately failed to prevent World War II, leading to its dissolution and the establishment of the United Nations in 1945.
