Which of the following is an example of a non-governmental organization (NGO)?

UNICEF is considered a non-governmental organization (NGO) because it operates independently of any government, despite receiving funding from governments and private donors. NGOs are typically established to address social, humanitarian, or environmental issues and work toward goals such as development, education, and health.

UNICEF, which stands for the United Nations Children's Fund, focuses on providing humanitarian and developmental assistance to children and mothers in over 150 countries. It advocates for child rights, provides healthcare and education, and supports initiatives aimed at enhancing children's well-being.

In contrast, organizations like the World Bank operate as international financial institutions and function under intergovernmental agreements, providing loans and funding to countries, making them part of the governmental framework rather than independent NGOs. The National Health Service is a publicly funded healthcare system in the UK, directly run by the government, while the Federal Bureau of Investigation is a federal agency of the US government responsible for law enforcement and domestic security. Thus, UNICEF stands distinctly as a non-governmental organization dedicated to its mission independent of governmental authority.
