C - Machines were used to produce goods on a large scale.
The Industrial Revolution dramatically changed America's economy, society, and culture. One of the primary ways it did this was through the widespread use of machines to mass-produce goods. This enabled production to take place on a much larger scale than ever before, making goods cheaper and more widely available. Factories sprang up all over the country, creating new jobs and drawing people into the cities. It also led to the growth of the transportation system, as goods needed to be transported from the factories to the markets. As a result of these changes, America underwent vast economic growth and became a world leader in manufacturing, setting the stage for future innovation and development. The other options mentioned in the question were not significant outcomes of the Industrial Revolution in America.
