The correct answer is:
D. The conference ignored existing boundaries when creating colonies, leading to territorial disputes after decolonization.
The Berlin Conference of 1884-1885 was held to lay down rules for the partition of Africa by European powers. The representatives of the European nations disregarded the existing ethnic, cultural, and political boundaries of African societies when creating new colonial territories. This artificial division has led to ongoing conflicts, ethnic tensions, and territorial disputes in many parts of Africa even after the decolonization process.
