Which of the following is NOT a main body of the United Nations?

The World Trade Organization (WTO) is indeed not a main body of the United Nations. The UN consists of several principal bodies that serve specific roles in promoting international cooperation and maintaining peace and security. The General Assembly, for example, is composed of all member states and serves as a deliberative assembly, making decisions on key issues including budgets and new member admissions. The Security Council has the primary responsibility for maintaining international peace and security, with the authority to impose sanctions or authorize the use of force. The International Court of Justice (ICJ) serves as the principal judicial organ of the UN, resolving legal disputes between states and providing advisory opinions on international legal issues.

In contrast, the WTO is an independent international organization that deals specifically with the rules of trade between nations. It operates independently of the UN structure, although it cooperates with various UN entities. This distinction highlights the unique roles and functions of each organization in the broader context of global governance.
