Which of the following aroused and promoted nationalistic feeling among Nigerians?

The option that aroused and promoted nationalistic feeling among Nigerians is "economic exploitation, racial discrimination, and political parties." This is because economic exploitation and racial discrimination led to a sense of injustice and inequality among Nigerians, which fueled their desire for independence and self-governance. Political parties were also instrumental in mobilizing Nigerians to demand for their rights and participate in the struggle for independence. The nationalist movements, such as the National Council of Nigeria and the Cameroons (NCNC) and the Action Group (AG), were formed in response to the injustices and discrimination faced by Nigerians, and they played a significant role in the push for independence.
