Farmers favored inflation because it would
a. increase crop prices.
b. lower the price of manufactured goods.
c. lower the cost of farm machinery.
d. increase their debt.

D- inflation would not increase the farmers debt, but (unless the debt is adjusted for inflation) the debt would decrease - this is not a correct answer.

Inflation is the decrease of the value of money (but the value of objects and services stays the same - it increases with the respect to the value of the money. Because of this neither the manufactured goods nor the farm machinery would be cheaper- but the  increase of crop prizes would take place (so answer a), and that's why farmers favour it.
