How did the idea of Aryan superiority make ordinary people's behaviour appear legitimate?

Correct answer: It presented unequal behaviour as natural and correct

Direct answer: Option A is correct. The idea of Aryan superiority claimed that one supposed racial group was naturally better and more deserving than others. When such an idea is repeated through schools, laws, speeches, posters, and institutions, unequal treatment can appear normal, scientific, or morally justified to ordinary people. The reasoning is: an ideological belief ranks groups; the ranking labels one group superior and others inferior; the state turns the belief into discrimination; repeated propaganda makes the policy seem legitimate. Option A correctly explains this process. Option B is wrong because Aryan superiority was not a belief in equality of all races. Option C is wrong because Nazi racial ideology restricted Jewish rights rather than expanding them. Option D is wrong because the idea supported and strengthened Nazi propaganda instead of ending it. Important distinction: an official claim that something is “natural” does not make it just or true. Memory cue: ideology can disguise discrimination as normal.
