The correct answer is B. European nations acquisition of uncolonized land.
Explanation
Imperialism is the way of one nation that usually has great power over world control and dominates others usually to take advantage of the resources of it or control its territory.
During the First World War, European powers began to focus on the African territory to establish their colonies since in the Far East and America many of their colonies had become independent. Therefore, Africa was distributed by European nations, who set in motion the extraction of natural resources for industry. On the other hand, another reason for this European imperialist tendency was the demonstration of greatness of the powers. So the correct answer is B. European nations acquisition of uncolonized land.
