Answer:
B. Railroads spurred the foundation and expansion of towns along the western rail route
Explanation:
Railroads built in the nineteenth century are a milestone in the history of American development. Prior to the construction of the railways, commercial production was primarily centered on regional markets. Railways connected cities, opening new consumer markets for products, enabling goods to be transported over long distances for the first time. As the railroads advanced, new cities developed around them. In addition, railroads have drastically reduced freight costs, making products cheaper and benefiting consumers. Therefore, the correct answer is that railways contributed to the expansion of cities along the railway route.
