Actually, there was an initial stock market crash that triggered a "panic sell-off" of assets. This was followed by unemployment, since over 13 million people were unemployed by 1932 and, as a result, there was a terrible impoverishment.

To sum up, the correct answer is letter "D": Tariff and War Debt Policies, Farming Crisis, Income inequality and lack of credit regulation.
