What Was Part of Europe's Role in the Great Depression

What was part of Europe's role in the Great Depression?

A) The German economy had come out the strongest after the Great War, taking competition away from American industry and forcing the United States to borrow from German banks.
B) Nations such as Great Britain, France, Spain, and Italy drastically increased their purchases of American goods as their economies began recovering after the Great War.
C) As a means of generating growth, the Federal Reserve Board only expanded the money supply, which thereby increased the amount of American money going abroad to Europe.
D) European nations who had been part of the Allies during the Great War proved unable to pay their war debts, and after the crash, American banks could no longer prop up their economies.
E) Because the United States had consistently refused to lend the Allies money during the Great War, European nations refused to lend the United States money as it plunged into its own financial crisis.
