A) It took government payments to railroads and gave them to farmers. B) It gave farmers shares in the largest railroad companies.
C) It prevented railroads from charging farmers more than other customers. D) It forced railroads to build lines to the largest farming areas.
 
Answer & Explanation Answer: C) It prevented railroads from charging farmers more than other customers.

Explanation:

In 1887 Congress passed the Interstate Commerce Act, making the railroads the first industry subject to Federal regulation. Congress passed the law largely in response to public demand that railroad operations be regulated.

 

Railroads discriminated in the prices they charged to passengers and shippers in different localities by providing rebates to large shippers or buyers. These practices were especially harmful to American farmers, who lacked the shipment volume necessary to obtain more favorable rates.
