Henry Clay's "American System" was primarily focused on promoting economic growth and development in the United States during the early 19th century. A key feature of this system was the emphasis on building a national infrastructure, which included the construction of a national highway system. This vision aimed to connect different regions of the country, facilitate trade, and promote economic interdependence among the states.

By advocating for the development of roads and canals, Clay believed that transportation improvements would enable goods and resources to move more efficiently and stimulate economic activity across the nation. This infrastructure was intended to support both industrial and agricultural sectors, ultimately fostering national unity and economic strength.

The other choices, while related to economic policy, do not capture the primary thrust of Clay's vision. The reduction of tariffs would run counter to the idea of protecting American industries, the establishment of a single currency was part of broader economic stabilization efforts but not a specific feature of the American System, and the promotion of agricultural exports, while important, was not as central to Clay's comprehensive plan as the emphasis on national infrastructure.
