The correct answer is: B. Security Council; two-third.
The United Nations (UN) is an intergovernmental organization that promotes international co-operation. A replacement for the ineffective League of Nations, the organization was established on 24 October 1945 after World War II in order to prevent another such conflict. At its founding, the UN had 51 member states; there are now 193. The organization is financed by assessed and voluntary contributions from its member states.
The UN’s objectives include maintaining international peace and security, promoting human rights, fostering social and economic development, protecting the environment, and providing humanitarian aid in cases of famine, natural disaster, and armed conflict. The UN’s six principal organs are the General Assembly, the Security Council, the Economic and Social Council, the Trusteeship Council, the International Court of Justice, and the UN Secretariat.
The General Assembly is the main deliberative organ of the UN. It is composed of all member states, each of which has one vote. The General Assembly meets in regular sessions every year, and in special sessions when necessary. The General Assembly’s functions include discussing and making recommendations on any matter within the scope of the UN Charter, initiating studies and making recommendations to promote international co-operation in the economic, social, cultural, educational, and health fields, and making recommendations for the peaceful adjustment of any situation that might lead to international friction or give rise to a dispute.
The Security Council is responsible for maintaining international peace and security. It is composed of 15 members, five of which are permanent members (China, France, Russia, the United Kingdom, and the United States) and 10 of which are elected by the General Assembly for two-year terms. The Security Council has the primary responsibility for the maintenance of international peace and security. It can adopt resolutions that are binding on all UN member states.
The International Court of Justice is the principal judicial organ of the UN. It is composed of 15 judges, who are elected by the General Assembly and the Security Council for nine-year terms. The International Court of Justice has jurisdiction to settle legal disputes between states, and to give advisory opinions on legal questions referred to it by UN organs and specialized agencies.
The UN Secretariat is the administrative organ of the UN. It is headed by the Secretary-General, who is appointed by the General Assembly upon the recommendation of the Security Council. The Secretariat is responsible for carrying out the day-to-day work of the UN.
The UN has played a significant role in international affairs since its founding. It has helped to prevent or resolve many conflicts, and has promoted human rights, economic development, and social progress around the world. The UN is an essential organization for maintaining international peace and security, and for promoting global co-operation.
In order for a new member to be admitted to the UN, the Security Council must recommend its admission, and a two-thirds majority of the General Assembly must vote in favor of its admission.
