The correct answer is B) were unable to repay their loans.
<em>When farmers income fell due to the low prices in the 1920s, they were unable to repay their loans.</em>
The Great Depression had a terrible impact on all the sectors of the American economy. After the stock market crash of October 1929, many people lost their jobs, many companies closed, and most of the banks went into bankruptcy. Farmers were heavily affected too. Farmers incomes fell to low levels, prices were dramatically reduced that they preferred to consume their crops instead of selling them. That is why, after the fall of their income, farmers were unable to repay their loans.
The other options of the question were a) produced more crops to repay their loans, c) received credit from banks to repay their loans, and d) received credit from the stock market to repay their loans.
