Answer:
D) Court cases to regulate interstate commerce to farmers' benefit were won with the aid of strong farmers unions.
Step-by-step explanation:
The rural economy in the 19th century was devalued and often did not promote good quality of life and fair prices for farmers, who had difficulties even to obtain financing for production.
However, at the end of this century with the expansion of the unions and the improvements they promoted to their sectors, farmers began to organize their own union that would pursue their interests. In this case, legal proceedings were initiated to regulate interstate commerce for the benefit of farmers and were won with the help of strong farmers' unions.
