Which of the following was not a demand of the nationalist movement in Nigeria?

The correct option is: "Withdrawal of military bases from African". During the nationalist movement in Nigeria, one of the major demands was the promotion of Africans to senior service positions. This was aimed at ensuring that Africans had greater representation and control in the colonial administration. Another demand was the increase of African representation in the legislative assemblies, as well as the improvement of conditions of service and salaries for Africans who worked in the colonial administration. Additionally, the reduction of the dictatorial powers of colonial officers was another demand of the nationalist movement in Nigeria. However, the withdrawal of military bases from Africa was not a demand of the nationalist movement in Nigeria. This is because the presence of military bases was not seen as a major issue during the struggle for independence.
