The answer is B. It created unnecessary projects just to employ people.
Farmers faced Native American raids, poor growing conditions, droughts, disease, insects, and anything that would give farmers a hard time now. Farmers had to pay higher prices for transportation which caused less profit - crops prices fell which also caused less profit. The government issued greenbacks then retired them, causing an increase in the value of money in the circulation.
