The correct answer is B, Germans eventually believed that Hitler would solve their economic problems, surged from the Great Depression.
Germany, which thanks to the Dawes Plan had managed to partially overcome the post-war crisis, was one of the most affected economies by the Great Depression. The withdrawal of the bank loans that it received from the United States, which had contributed to the reconstruction of its economic fabric, resulted in the bankruptcy of innumerable companies.
German banks closed their doors for several days in July 1931 in fear of an avalanche of desperate customers to dispose of their savings. That same year one of the most important banks in Austria, the Kredit Anstalt, went bankrupt (its accounts represented 70% of the country's bank funds). Many more followed.
The Weimar Republic faced the problem of unemployment (6 million unemployed in 1936) and a growing social tension expressed in virulent protests, encouraged both from the left and from the right.
The lack of a colonial empire of its own (Germany had been stripped of its dominions in the wake of the war) prevented the creation of an integrated commercial space that would have partially alleviated the effects of the recession.
Faced with the impossibility of facing the war compensations imposed by the victors, the American president Hoover, in an attempt to avoid the collapse of the German economy, granted in 1931 a one-year moratorium on payments. The initiative was totally useless, because the German banking system could not prevent the collapse.
All these situations of economic and social crisis gave rise to the Nazi movement, a nationalist movement that took advantage of the heated moment in their country to win supporters.
Germany managed to get out of the crisis thanks to the intervention of the State, totally controlled from 1933 by the Nazis. These faced the depression with an emphasis on job creation, investment in public infrastructure and a huge development of the arms industry.
