Nigeria is a major financier of which of the following?

Analyze the question: The question asks which organisation Nigeria is a major financier (a leading financial contributor) of. This is about Nigeria's role in international organisations.

Explain the concept:

• IBRD (International Bank for Reconstruction and Development, part of the World Bank): the biggest contributors are the USA, Japan, China, Germany, and so on. Nigeria is a member and borrower, not a major financier.
• AFDB (African Development Bank): Nigeria is the largest shareholder among the regional (African) members and one of the biggest contributors to the bank. Nigeria also funds the African Development Fund (ADF), the AfDB's soft-loan window, and the Nigeria Trust Fund (NTF), set up in 1976 to give concessional loans to poorer African countries.
• UNO (United Nations Organisation): the largest funders are the USA, China, Japan, and Germany. Nigeria pays dues but is not a major financier.
• OPEC: Nigeria is a member and a major oil producer, but OPEC is funded by member contributions and Nigeria is not singled out as its major financier. Saudi Arabia plays the dominant role.

Solution:

1. Eliminate IBRD and UNO, since they are dominated by Western and Asian economies.
2. Eliminate OPEC, since Nigeria is a member and producer, not its main financier.
3. Nigeria's well-known financial role in Africa is through the African Development Bank and its Nigeria Trust Fund. This matches the question's wording.

Answer: The correct option is B. AFDB.

Exam tip: When a question says "major financier" and the options include an African institution, think of Nigeria's regional leadership role: AfDB, ECOWAS, and the Nigeria Trust Fund. Also remember that Nigeria is the largest African contributor to the AfDB, which is a frequent JAMB Government fact.
