The African Development Bank was set up in 1964 and has its headquarters in

Analyze the question: This is a factual recall question about the African Development Bank (AfDB): where its headquarters is located.

Explain the concept: The AfDB was established in 1964 (it began operations in 1966) to promote economic development and social progress in African countries through loans, grants, and technical assistance. Its headquarters were set up in Abidjan, the economic capital of Ivory Coast (Côte d'Ivoire).

Step by step:

1. Burkina Faso: its capital is Ouagadougou. It hosts other regional bodies, but not the AfDB.
2. Ivory Coast: the AfDB's headquarters were in Abidjan. ✔
3. Liberia: Monrovia does not host the AfDB.
4. Niger Republic: Niamey does not host the AfDB.
5. Senegal: Dakar hosts other organizations, but not the AfDB.

Note on timing: The AfDB temporarily relocated to Tunis, Tunisia, from 2003 to 2014 because of political instability in Ivory Coast. It returned to Abidjan in 2014.

Answer: B. Ivory Coast

Exam tip: Remember "AfDB = Abidjan" because both start with "A". Also note that ECOWAS is headquartered in Abuja, Nigeria, and the ECOWAS Bank for Investment and Development (EBID) is in Lomé, Togo. These are often tested together.
