Final answer:
Bimetallism would benefit farmers by increasing the money supply and potentially leading to higher prices for crops due to inflationary effects.
Step-by-step explanation:
How would bimetallism benefit farmers? Bimetallism, the use of two metals such as gold and silver for currency, would most likely benefit farmers by increasing the money supply and potentially increasing prices for crops. This inflationary effect would allow farmers to earn more money to spend on higher-priced goods, which they had been facing due to high tariffs on industrial products. As a result, letter c is the correct answer as it would increase the money supply, and letter d could be a potential indirect benefit, as it would increase prices for crops due to the resulting inflation from a larger money supply.
