Nazi policy towards disabled people was based on which dangerous belief?

Correct answer: Some lives can be considered less valuable

Direct answer: D, some lives can be considered less valuable. Nazi racial ideology ranked human beings according to an invented idea of biological worth and treated disabled people as burdens or as threats to an imagined healthy national body. This is called dehumanisation: people are denied equal dignity and are judged by usefulness, health, or conformity instead of being recognised as persons with rights. The reasoning is: a false hierarchy labels some lives inferior; that label is repeated through propaganda and policy; discrimination and forced measures then become easier to justify. A is wrong because equal dignity is the ethical principle that Nazi policy violated. B is wrong because Nazi authorities exercised extreme control over individuals. C is wrong because Nazi rule was dictatorial and anti-democratic. D identifies the dangerous assumption behind the persecution. Memory cue: whenever a policy ranks people by supposed human worth, identify dehumanisation and reject it as a violation of equal rights.
