The answer is the Stock Market Crash. The Weimar Republic already had to pay a tribute for the war. America decided to loan Germany money to help it pay back the tributes. After the Stock Market Crash America wanted the money back and Germany had to print money. This event caused the economy in Germany to crash.
I believe it is C stock market crash, because the question has the answer in it, it says economic crash so it would go with stock market crash
