Answer:
Option D. The international organization known as the United Nations is the organization that has nearly 200 member nations, 15-nation security council and has United States as a permanent member.
Step-by-step explanation:
Founded on October 24th, 1945, in San Francisco at the "United Nations Conference on International Organizations" the United Nations became a global organization that was made as a result of the Second World War, and in a collective international effort of securing the international peace and to achieve international co-operation.
Today out of the 195 countries in the world, 193 are members of the United Nations, with the exceptions of the state of Palestine and the Vatican.
The Security Council is perhaps the most important organ of the organization as it has the responsibility to maintain global peace and security. It has 15 members, 10 non-permanent and 5 permanent, with the United States being one of the 5.
