the third reich based its power primarily on\n○ fear.\n○ censorship.\n○ laws.\n○ incentive.

Brief Explanations:

The Third Reich, under Nazi - Germany, used fear as a primary means to maintain power. Through secret police (Gestapo), concentration camps, and mass terror, the regime instilled fear in the population. Censorship was a tool but not the primary basis of power. Laws were often used to enforce the regime's ideology but were also secondary to fear. Incentives were not the main way of maintaining power.

Answer:

fear.
