One of the major defects of the Nigerian council which necessitated its replacement was that....
the meetings of the council were poorly attended
the council could only make law for the southern protectorate
the executive council was powerful than it
the council was unrepresentative
Correct answer is D
The unrepresentative nature and figurehead stance of the Nigerian Council's membership is a stand-alone reason for the flaw of the platform. Most members were Whites who didn't understand the interests of the people they seek to govern.
