Answer:
a) giving factories easier access to natural resources from around the country.
Explanation:
The spread of railroads during the 19th century greatly contributed to the industrialization of the country. Before railroads became widespread, businesses needed to operate locally, and this meant that their access to natural resources was very limited. However, as transportation became faster and more easily available, new sources became an option. Factories had an easier access to natural resources from around the country, making production cheaper and more efficient.
