Answer:
The correct answer is C. The canals helped the Midwest to become a major center of American textile production in the early 1800s.
Explanation:
The canals are civil engineering constructions that are carried out with the aim of connecting two or more bodies of water, facilitating the transfer of merchant ships and transport vessels.
In the 1800s, many canals were built between the different bodies of water in the nation, with the aim of creating trade routes that would allow economic exploitation of the most remote regions of the country. Thus, the most important of these was the Erie Canal, completed in 1825, which made it possible to connect the Great Lakes with the ports of the East Coast in New York State.
This canal, which reaches the city of Buffalo, allowed the development of the Midwest as one of the main industrial regions of the nation, facilitating the transport of products manufactured in that region to international markets through the port of New York.
