Correct answer
Explanation
The United Nations Organization (UNO) officially came into existence on October 24, 1945, after the UN Charter was ratified by China, France, the Soviet Union, the United Kingdom, the United States, and a majority of other signatories. This date is now celebrated as United Nations Day. 1946 is incorrect as it marks the first General Assembly, while India's independence (1947) and the start of the Republic of India (1950) are unrelated to the UN's founding.
