the railroads became a model of efficiency for other industries to follow.

The correct answer is A) Businesses were able to expand their operations and reach new markets.

Explanation:

This is true for both Europe and the United States.  During the 1800s the United States was still a young country which was looking to expand west and south wards.

With huge distances, there were very few urban centers and it was difficult to do business.

With the arrival of Railroads, far flung small towns and villagers were connected with the industrialized North-east of the country.

Businesses were able to expand their operations and sell their products into new and growing towns.

There was a huge boom in business as two-way trade became easier and cheaper.
