The correct answer is D. Indigent
Explanation
Imperialism was a social, cultural, political, and economic phenomenon of the early nineteenth century in which the main powers began to explore, conquer and colonize the territory of Africa, Asia and Oceania. During this time, Europeans took advantage of the natural resources that were in those continents to promote the industrial revolution. This harmed the native communities of this continent that left them in a state of indigent (poverty and misery). However, Europeans did not feel any responsibility for this condition but instead considered it to be a natural matter. Therefore, the correct answer is D. Indigent
