Why was the combination of economic crisis and nationalist humiliation effective in Hitler’s rise?

It turned public anger toward Nazi nationalism

The Great Depression brought unemployment, business failures, falling incomes, and insecurity to Germany, while the Treaty of Versailles was widely associated with military restrictions, territorial losses, reparations, and national humiliation. The Nazis connected these different grievances in a simple political message: they claimed that the Weimar leaders had failed and promised to restore order, jobs, national strength, and pride. This did not mean that every German supported Hitler or that the crisis automatically caused Nazism; Nazi organization, propaganda, elite support, and political manoeuvring also mattered. Nevertheless, option A best explains the combination, because it shows how suffering and resentment were redirected toward aggressive Nazi nationalism.
