The correct answer is the North and Midwest.

Henry Clay's American system was an economic plan which focused on protecting and developing American industry and transportation. The goal of this system was to turn America into an industrial superpower. This plan consisted of three main points including:

1) A protective tariff- This would increase the price of foreign goods, which would benefit American businesses.

2) Provide subsidies to infrastructure projects (such as the development of canals, railroads, etc.)

3) A national bank to monitor and help commerce grow.
