The correct answer is 4. By implementing tariffs for foreign trade.

During the Industrial Revolution, the United States government implemented tariffs on imported goods to protect and promote domestic industries. These tariffs made it more expensive for foreign competitors to sell their products in the US market, effectively discouraging competing markets outside the US. This was often done under the belief that it would promote economic growth and self-sufficiency within the country.
