The correct answer is C) suggested that the fittest societies would prevail.
Social Darwinism supported Nazi ideology in that it suggested that the fittest societies would prevail.
Social Darwinism was adopted by the Nazi ideology during its tenure in Germany during the 1930s and 1940s. The Nazi genocide is one example of the idea of supreme race that the Germans had in those years. The ideas of the Nazi to mark Jewish with a yellow star of David was humiliating and then massive killing of Jews in the camps, was an atrocity.
