D. Increased number of labor unions

Final answer:

Railroad industry growth directly led to increased settlement in the West, industrial expansion, and the rise of labor unions.

Explanation:

Increased settlement in the West was a direct result of the growth of the railroad industry. The expansion of railroads allowed for easier transportation and access to the Western states, leading to increased migration and settlement in those regions.

Moreover, as railroads facilitated the movement of people and goods, they played a key role in industrial expansion, including the rise of steel manufacturing, the telephone, and other technologies, as well as the growth of labor unions due to the working conditions in factories.

Additionally, the growth of the railroad industry spurred economic development and helped transform America from a rural country to urban centers, propelling its growth and economic status during the industrial revolution.
