Concept:The correct protocol is the one that directly addresses unrestricted movement of people, goods, and services inside the ECOWAS region.
Explanation:The Economic Community of West African States (ECOWAS) has several legal instruments for regional integration.
The question asks specifically for the protocol that covers movement of persons, goods, and services.
The ECOWAS Trade Liberalization Scheme mainly deals with trade in goods and tariff reduction.
The Abuja Agreement relates to political and security issues, not free movement.
The Treaty of Lagos established ECOWAS but is not the protocol on movement.
The Protocol on Free Movement (formally the Protocol Relating to Free Movement of Persons, Residence, and Establishment) is the framework that enables citizens to move, reside, and trade across member states.
Therefore, it is the protocol that allows free movement of persons, goods, and services.
Answer:B. The Protocol on Free Movement
