The correct option is D. Nigerian Export-Import Bank. Explanation of the Correct Answer The Nigerian Export-Import Bank (NEXIM) is a financial institution specifically established to promote and facilitate international trade in Nigeria. Its primary role is to support the growth of Nigeria's export sector, which is crucial for enhancing the country's trade balance and economic development. Here’s a detailed breakdown of why this option is correct:

1. Purpose of NEXIM: NEXIM was created to provide financial assistance to exporters and importers, thereby boosting Nigeria's trade with other countries. It offers various services, including loans, guarantees, and insurance to mitigate risks associated with international trade.
2. Focus on Exports: The bank's main focus is on increasing the volume of exports from Nigeria, which is vital for generating foreign exchange and improving the country's economic standing globally. By providing financial support, NEXIM helps local businesses expand their reach into international markets.
3. Government Support: NEXIM operates under the auspices of the Nigerian government, which recognizes the importance of trade in driving economic growth. The bank collaborates with other government agencies to create a conducive environment for trade.
4. Developmental Role: Beyond just financial services, NEXIM plays a developmental role by providing advisory services to exporters, helping them understand international markets, and ensuring they meet the necessary standards for their products.

Explanation of Why Other Options Are Incorrect Now, let’s analyze the other options to understand why they are not the correct answer: A. Nigerian Deposit Insurance Corporation (NDIC): - Function: The NDIC is primarily focused on protecting depositors by insuring deposits in banks and other financial institutions. Its main role is to promote confidence in the banking system, not to facilitate international trade. - Conclusion: While important for financial stability, the NDIC does not have a mandate related to boosting trade. B. Nigerian Economic Reconstruction Fund (NERF): - Function: This fund was established to support economic recovery and development projects within Nigeria, particularly after periods of economic downturn. However, it does not specifically target trade facilitation. - Conclusion: NERF is more focused on reconstruction and development rather than directly enhancing trade. C. Nigerian Industrial Development Bank (NIDB): - Function: The NIDB was established to provide financial support for industrial development in Nigeria. While it does contribute to the industrial sector, its focus is not exclusively on trade or exports. - Conclusion: The NIDB supports industrial projects but does not specifically aim to boost Nigeria's trade with the rest of the world.
