Use of pseudo-science in the Nazi worldview increased which danger?

Danger of making discrimination look like scientific truth

Option A is correct because pseudo-science uses the appearance and vocabulary of science to support claims that have no reliable scientific basis. Nazi racial theories falsely ranked people into superior and inferior groups and misused ideas about heredity, biology and selection to defend antisemitism, forced sterilisation and persecution. Presenting prejudice as scientific fact made discrimination seem objective, inevitable and respectable, allowing the state to impose harmful policies with less public questioning. Options B, C and D are not dangers produced by Nazi pseudo-science. It did not expand democratic rights, create peace or spread equality; it provided a deceptive justification for racism and exclusion.
