C. The United Nations shapes global affairs by providing a way for nations to discuss global affairs and set goals. It acts as a platform for member nations to come together and address various global issues such as peace and security, human rights, and sustainable development. Through its General Assembly, Security Council, and various specialized agencies, the UN facilitates dialogue, negotiation, and cooperation among member states to shape global policies and promote international cooperation.
