Final answer:
The Nazis used the Gestapo, SS, and police and courts to control Germany, but 'Police and Schools' as an option is not a specific organization used by the Nazis for control. Hence, the correct answer is option D.
Step-by-step explanation:
The organization that was NOT used by the Nazis to control Germany out of the options provided is D) Police and Schools. The Nazis did employ a variety of tactics to monitor and control the population, including the Gestapo, SS (Schutzstaffel), and the police and courts. The Gestapo served as the secret police within the SS, and both were critical in the enforcement of Nazi policies.
Meanwhile, courts were also manipulated to enforce Nazi ideology. However, Police and Schools as an entity does not represent one of the organizations used by the Nazis for control. Instead, the Nazis reorganized the education system for indoctrination purposes and used separate organizations such as the Hitler Youth to influence young Germans directly.
