Which false scientific theory did the nazis use to justify their persecution of jews? a. mysticism b. phrenology c. racism d. astrology

The correct answer is Racism.

This concept revolves around the idea that a specific group of humans are superior to others based on their race. This idea drove Nazi propaganda during World War II, as Hitler's focus was to create an "ideal" Aryan race. The only way this would be possible was by eliminating other races through extermination policies.
