Answer:
d. Germany industrialists who were getting rich off of the economic boom in Germany post World War I
Explanation:
The Republic of Weimar was the political regime and, by extension, the period of the history of Germany between 1918 and 1933, after the defeat of the country in the First World War. The name of Weimar Republic is a term applied by later historiography, since the country retained its name of Deutsches Reich ('German Empire'). The denomination comes from the homonymous city, Weimar, where the constituent National Assembly met and the new constitution was proclaimed, which was approved on July 31 and entered into force on August 11, 1919.
This period, although democratic, was characterized by great political and social instability, in which there were military and right-wing coups, revolutionary attempts on the part of the left and strong economic crises. All this combination led to the rise of Adolf Hitler and the National Socialist Party. On March 5, 1933, the Nazis obtained the majority in the elections to the Reichstag, with which they were able to approve the enabling act on March 23, together with the Decree of the Reichstag fire on February 28 and by allowing the approval of laws without the participation of Parliament, it is considered to have meant the end of the Weimar Republic. Although the Weimar Constitution of November 11, 1919 was not revoked until the end of the Second World War in 1945, the triumph of Adolf Hitler and the reforms carried out by the National Socialists (Gleichschaltung) invalidated it much earlier, establishing the called Third Reich.
