Correct answer:
B. Security Council
Historical details:
When the United Nations was formed in 1945, the five permanent members assigned to the UN Security Council were the nations which had been victorious in World War II: The United States, the United Kingdom, France, the Soviet Union, and the Republic of China. Essentially, those same five remain the permanent members of the Security Council today, except that, since 1971, the People's Republic of China has been recognized by the UN as the legitimate government of China; and since the USSR dissolved in 1991, the Russian Federation has been recognized as the legal successor state, with UN and Security Council membership.
At the present time, there are also 10 additional seats on the Security Council for non-permanent member nations, which are elected to the Security Council by the UN General Assembly for two-year terms.
The powers of the Security Council include establishing peacekeeping operations and authorizing military action. The Security Council also has authority to impose sanctions against nations.
