Step-by-step explanation:
The United Nations Security Council is comprised of 15 member states. To answer the question directly, there are 10 non-permanent members that make up the U.N. Security Council, and their terms last for 2 years. This means the correct answer to the student's question is D) 10 members, 2-year terms. The Security Council is an important body within the UN, charged with maintaining global peace and stability. It has the power to make decisions that are binding on all member states. Apart from the 10 non-permanent members, there are also five permanent members, sometimes referred to as the P5, which include the United States, United Kingdom, France, Russia, and the People's Republic of China (PRC). These members have the unique power to veto actions, effectively controlling the Security Council's resolutions.
