Final answer:
The United States and other member nations confront issues such as international peace, security, and development within the United Nations (UN), an international organization founded in 1945 after World War II. Therefore, the correct answer is option H. The United Nations.
Step-by-step explanation:
In which organization do the United States and other member nations confront problems like maintaining international peace and security, developing friendly relations among nations, and promoting social progress, better living standards, and human rights? The answer is H. The United Nations.
The United Nations (UN) is a paramount international organization, established in the aftermath of World War II, with the core aims of preventing future conflicts and fostering global cooperation. The UN includes multiple bodies like the General Assembly and the Security Council, where issues such as peace and security, admissions of new members, and budget are decided. It also has specialized agencies like the World Health Organization and World Bank that work to promote economic development and tackle global challenges.
Representatives from member nations, including the United States, routinely meet within the framework of the UN to address a wide range of issues facing the international community. Non-member entities cannot directly confront these problems within the UN as the organization is comprised of sovereign states, making options F, G, and J incorrect in this context.
