Correct answer: C. To justify racial struggle and superiority
Explanation: Darwin’s theory described natural selection in living organisms; it did not rank human groups as morally or politically superior. Nazi thinkers distorted such ideas and applied them to society. They falsely claimed that human beings were divided into unequal races and that struggle between races was natural, desirable, and necessary for the strongest group to dominate.
This misuse of scientific language is often called Social Darwinism or pseudo-science. It was used to support racism, persecution, and the supposed superiority of the so-called Aryan race. Therefore, option C is correct. Options A, B, and D contradict the Nazi worldview because it rejected equality, democracy, and peaceful coexistence.
