Name one of the principal organs of the UN.

The Security Council is indeed one of the principal organs of the United Nations. It was established to maintain international peace and security, and it plays a crucial role in addressing global conflicts. The Council has the authority to implement measures such as sanctions or authorize the use of force to ensure peace is maintained. It is composed of 15 members, with five permanent members—China, France, Russia, the United Kingdom, and the United States—who have veto power over substantive decisions.

In contrast, other options, while significant in international relations and humanitarian efforts, are not principal organs of the UN. The World Health Organization focuses on global health issues as a specialized agency of the UN but does not hold the same foundational status as the Security Council. The International Red Cross operates independently and is part of the broader humanitarian movement but is not a UN organ. Similarly, the North Atlantic Treaty Organization is a military alliance and not aligned with the UN’s structure, although it may collaborate with the UN on certain issues.
