The correct answer is D. The Erie Canal provided a source of transportation for goods and people.

Explanation:

The Erie Canal was inaugurated on October 26, 1825 and connects Albany along the Hudson River with Buffalo, located on the Niagara River in New York State.

This connection was first proposed in 1699 but its construction began in 1817. About 584 km long, it has a total of 36 locks and a total height difference of 172 meters.

The canal allowed the boats access to the large inland lakes from New York City, thus becoming an important trade route, allowing the Big Apple to overtake the city of Philadelphia as a commercial port. It was the first transportation system between the eastern coast and the western interior of the United States that did not require portage.

Nowadays it is used to a greater extent for tourism purposes.
