Which of the following is not an objective of ECOWAS?

The objective of ECOWAS that is not listed among the options is the promotion of a common language. ECOWAS is the Economic Community of West African States, a regional intergovernmental organization that aims to promote economic integration among its member states in West Africa. ECOWAS has several objectives, including the improvement of infrastructure, the encouragement of free movement of people, and the promotion of trade among member countries. However, the promotion of a common language is not listed as an objective of ECOWAS. While some member states share a common language, such as English or French, there is no official language of the organization. Therefore, the objective of promoting a common language is not a priority of ECOWAS.
