Final answer:
The United Nations is the example of an international government organization among the options given. It has various bodies like the General Assembly and the Security Council, and it works to maintain international peace and promote human rights and social progress.
Step-by-step explanation:
The international government organization among the options provided is the United Nations (UN). Founded in 1945, the UN is committed to maintaining international peace and security, developing friendly relations among nations, and promoting social progress, better living standards, and human rights. This influential organization includes various institutional bodies like the General Assembly and the Security Council. The Security Council is particularly significant as its decisions related to international peace and security are binding on all member states.
The World Wildlife Federation, Red Cross, and Amnesty International are all examples of non-governmental organizations (NGOs) rather than international government organizations. These NGOs play crucial roles in global governance, with some advocating for humanitarian aid, environmental conservation, and human rights issues, respectively. Notably, Amnesty International has had a profound impact on the adoption of international human rights treaties, demonstrating the power NGOs can have in influencing global policies.
