Concept:ECOWAS is an economic union aimed at regional cooperation and development among West African states.
Explanation:ECOWAS was formed to promote economic integration across West Africa.
Its main focus is to remove trade barriers and encourage the free movement of goods, services, and people.
Therefore, it seeks to foster exchange of goods and services among member countries.
A market for stocks and shares is unrelated to ECOWAS’s core objective.
A common political system is not part of ECOWAS’s aims.
A common transport policy is too narrow and not a primary aim of ECOWAS.
Thus, the correct option is the one that matches ECOWAS’s economic goal.
Answer:C. foster exchange of goods and services
