Answer:
B. Economic problems caused by hyperinflation
Step-by-step explanation:
After the First World War, the Germans were humbled by the harsh penalties imposed by the Treaty of Versailles, which ruled Germany guilty of the war and blamed the country for all economic reparation.
The Treaty of Versailles generated a feeling of anger and frustration in Germany, which was potentialized in the face of the economic crisis caused by hyperinflation. Economic catastrophe has reduced people's standard of living and fueled nationalist sentiment that has boosted Hitler's rise to Nazism and totalitarianism.
