Henry Clay's American System had high taxes on imported goods. How would that benefit the Western and Southern Territories? • He thought that the taxes would help Southern farmers to ship things North • He thought that Southerners would get more money from the taxes being collected • He thought that the taxes would fund a cross-country road system O He thought that Northerners would buy goods from the West and South to avoid paying high taxes

The last option, "He thought that Northerners would buy goods from the West and South to avoid paying high taxes," is the most accurate. Henry Clay believed that the high taxes on imported goods would encourage Northerners to purchase goods from within the country, particularly from the Western and Southern territories. This would ultimately benefit the Western and Southern territories by boosting their economies and creating a market for their products.
