Which organization is commonly classified as an extremist organization?

• A. UNICEF
• B. World Bank
• C. Al-Qa'ida
• D. NATO

Answer: (C)

Extremist organizations are groups that openly advocate or use violence to pursue political goals and are widely designated as terrorist or extremist by governments and international bodies. Among the options, Al-Qa'ida fits this profile: it has carried out and promoted international terrorist attacks and is widely listed as a terrorist/extremist organization by many countries and international organizations. The other choices operate within established international systems: UNICEF is a UN agency focused on children's welfare, the World Bank is an international development financier, and NATO is a political-military alliance. None of these are classified as extremist.
