Correct Option: B. Increased trade among members Detailed Explanation: The Economic Community of West African States (ECOWAS) was established in 1975 with the primary aim of promoting economic integration and cooperation among its member states. One of the most significant achievements of ECOWAS has been the increase in trade among its member countries. Here’s a step-by-step breakdown of why option B is the correct answer:

1. Trade Liberalization Initiatives: ECOWAS has implemented various trade liberalization policies, such as the ECOWAS Trade Liberalization Scheme (ETLS), which allows for the free movement of goods among member states without tariffs. This has significantly boosted intra-regional trade.
2. Common External Tariff (CET): The introduction of a Common External Tariff has helped standardize tariffs on goods imported from outside the region, making it easier for member states to trade with each other. This has encouraged local production and reduced dependency on external markets.
3. Regional Market Development: By creating a larger regional market, ECOWAS has facilitated the growth of businesses that can now access a wider customer base. This has led to increased economic activity and investment within the region.
4. Trade Agreements: ECOWAS has entered into various trade agreements with other regional and international bodies, further enhancing trade opportunities for its members. These agreements have opened up new markets for West African products.
5. Infrastructure Development: ECOWAS has also focused on improving infrastructure, such as transportation and communication networks, which are crucial for facilitating trade. Better roads, ports, and communication systems have made it easier for goods to move across borders.

Why the Other Options Are Weaker:

• A. Free movement of persons and right of residence: While ECOWAS has made strides in promoting the free movement of people, this aspect has not been as fully realized as trade. There are still significant barriers and challenges, such as immigration policies and security concerns, that limit the free movement of persons compared to the progress made in trade.
• C. Political integration of the region: Political integration remains a complex and challenging goal for ECOWAS. While there have been efforts to promote political stability and cooperation, the region still faces significant political challenges, including conflicts and governance issues. Thus, political integration is not as advanced as economic integration through trade.
• D. Providing financial aid to members: Although ECOWAS does provide some financial assistance to member states, this is not its primary focus or a significant area of progress compared to trade. Financial aid is often limited and does not have the same impact on economic growth and integration as increased trade does.

Revision Summary:

• ECOWAS has significantly increased trade among its member states through initiatives like the ETLS and CET.
• Trade liberalization has created a larger regional market, boosting local production and investment.
• Infrastructure improvements have facilitated easier movement of goods across borders.
• Other areas like free movement of persons, political integration, and financial aid are less developed compared to trade initiatives.
