A and C
Since the Germans had to pay reparations to the allies because of the treaty of Versailles, their economy was very bad and people wanted to fight back, so when hitler came to power and told the germans that he can help them, he basically put gasoline on a already lit fire. the germans supported him a lot and hoping he can help Germany be the country it used to be before the allies made it what it was. (hope this makes sense and was not too late)
