The correct answer is B. Ten.
The United Nations Security Council (UNSC) is one of the six principal organs of the United Nations. It has 15 members, five of which are permanent members (China, France, Russia, the United Kingdom, and the United States) and ten of which are elected by the General Assembly for two-year terms.
The non-permanent members of the UNSC are elected by the General Assembly on a regional basis, with five seats each for Africa, Asia, Latin America and the Caribbean, and Western Europe and Others. The ten non-permanent members are elected every year, and no country can serve more than two consecutive terms.
The UNSC is responsible for maintaining international peace and security. It has the power to adopt resolutions that are binding on all UN member states. The UNSC also has the power to establish peacekeeping operations and to authorize the use of force.
The UNSC is often referred to as the “most powerful body in the world” because of its ability to adopt resolutions that are binding on all UN member states. However, the UNSC has been criticized for its lack of effectiveness, particularly in the face of vetoes by the permanent members.
