The correct answer is B. Social Darwinism

Explanation:

Social Darwinism was a doctrine that tried to apply the principles of evolution and the concept of the "fittest" into human society. This proposed certain individuals and certain human races had evolved to become superior to others, and therefore superior races and individuals should dominate others. Moreover, this doctrine supported the idea those that were not fit needed to be eliminated, which makes this doctrine too radical, discriminatory, and immoral. According to this, the idea that certain races should conquer because these are genetically better is related to Social Darwinism.
