What was the main effect of linking the body with race in Nazi biology teaching?

Correct answer: Children learned to see humans by racial value

Nazi biology teaching did not treat the body as only a matter of personal health. It connected physical features, heredity, and supposed racial categories with ideas of human worth. In this way, children were encouraged to believe that people could be ranked as superior or inferior according to race. This attacked the principle that all human beings have equal dignity and rights. The teaching therefore helped prepare young people to accept exclusion, discrimination, and persecution as if they were natural or scientific.

Choice C follows because it directly describes the social and political effect of this false racial teaching: children learned to judge human beings by an invented racial value. Choice A is wrong because the body was made a public and political concern, not a private one. Choices B and D do not describe the purpose or result of Nazi racial education. The key point is that Nazi ideology misused biology to justify racism and inequality.
