Which of the following is not a specialized agency of the United Nations Organization?

The General Assembly is not a specialized agency of the United Nations Organization. The United Nations (UN) is made up of various bodies, including specialized agencies that focus on specific issues. These specialized agencies are autonomous organizations that work with the UN to achieve its goals. The World Health Organization (WHO), the Food and Agriculture Organization (FAO), the International Labour Organization (ILO), and the International Bank for Reconstruction and Development (IBRD) are all specialized agencies of the UN. However, the General Assembly is a principal organ of the UN, which is made up of all member states and serves as a forum for member states to discuss and coordinate on international issues.
