Concept:ECOWAS promotes regional integration by easing travel restrictions among member states.
Explanation:The ECOWAS Protocol on Free Movement of Persons allows citizens of member countries to travel freely within the region.
Under this protocol, visa requirements are waived for citizens of member states.
This means a citizen can enter another member country without a visa and stay for a limited period.
This policy encourages cross-border trade, movement, and stronger regional unity.
Option A is incorrect because border posts do not ease movement.
Option C is incorrect because ECOWAS has not adopted a single currency for all members.
Option D refers to maintaining peace and security, which does not directly address the movement of persons.
Therefore, the correct answer is option B.
Answer:B. waived visa requirements for citizens of member countries.
