Answer:
C. Europeans believed they had the right to conquer other lands because their culture was superior.
Step-by-step explanation:
Social Darwinism when relating to imperialism is best described as the view that the colonizers were "better" in some way than the inhabitants of they land they were colonizing. This is present in Asian colonization as well as African colonization in the late 19th century by European powers. It was only natural to see yourself as more sophisticated as a European at the time; most European imperialists used the argument of social Darwinism to say that they had a right to conquer foreign lands, since their way of life (as well as culture!) was superior.
