Concept:Nationalism in Nigeria grew from events that raised political awareness and opposition to colonial rule.
Explanation:The Atlantic Charter inspired oppressed people to seek self-determination.
The activities of the superpowers during the Cold War encouraged decolonisation.

The colonial administration gave no real favours; rather, its exploitative policies provoked nationalist agitation.
Thus, the option that is NOT a factor is "Colonial favours from overload".
Answer:Option D.
