Answer: A- It was the first time the federal government regulated a private industry.
Step-by-step explanation:
In 1887, Congress passed the Interstate Commerce Act, making the railroads the first industry subject to federal regulation. After the civil war railroads were privately owned and entirely unregulated. Each company held a natural monopoly, so they were regarded with distrust by much of the public, who charged them with anything from forming monopolies and wielding corrupt political influence
Hope this helps have a great day :)
