Which of the following is not a problem of ECOWAS?

The problem that is not associated with ECOWAS is "Diversified economy for West Africa". ECOWAS, which stands for the Economic Community of West African States, is a regional organization of 15 West African countries established to promote economic integration in the region. The other options listed are all problems that ECOWAS faces in achieving its objectives. Different levels of economic development in member countries, different economic policies, transportation and communication links, and use of different currencies can all pose challenges to the integration process. However, "diversified economy for West Africa" is not a problem but rather a desirable goal for the region.
