Final answer:
Herbert Macaulay's quote from 1905 reflects the sentiments that would become part of the Pan-African Movement. This movement aimed to unify African peoples and resist colonialism and racial discrimination.
Step-by-step explanation:
The quote from Herbert Macaulay, dating around 1905, reflects a critical view of colonial British governance in Nigeria, suggesting that the alleged 'true interests of the natives' were secondary to the economic benefits to the colonizers. This critical perspective is indicative of sentiments that would fuel later movements for independence and civil rights across the colonized world. The best description of the feelings that began the political, economic, and social movement decades later, in this case, is the Pan-African Movement (Option B). The movement sought to unify African people, globally combat colonialism, and claim their rights and freedoms. It wasn't confined to a single nation like the Mau Mau Rebellion or focused on a specific policy like the Anti-Apartheid Movement. The Pan-African Movement encompassed the ideological struggle against imperialism and racial discrimination relevant to Macaulay's critique.
