The correct answer is B.
The nazi party, leaded by Hitler, blamed Jews for all the miseries that the German people were suffering since the end of WWI. Jews were blamed by Hitler for the defeat of Germany at war and for having signed the humilliating Versailles Treaty after the conflict.
Jews were mostly rich while Germans had lost everything during the crisis. German people believed those arguments and started to share Hitler's antisemitic ideas too and to support all the discriminatory legislation that nazis started to enact when they reached power.
