Answer :
Final answer:
Evidence of post-War of 1812 American nationalism is present in various measures but not in a reduction in tariffs, as this period actually experienced the introduction of a protective tariff to encourage domestic manufacturing and reduce dependence on foreign imports.
Explanation:
Evidence of post-War of 1812 American nationalism can be seen in several aspects, except for a reduction in tariffs to encourage the resumption of imports. After the War of 1812, there was a surge of American nationalism characterized by a more assertive foreign policy, a celebration of republicanism, support for economic expansion, and a series of Supreme Court decisions that increased federal authority, such as Dartmouth College v. Woodward, McCulloch v. Maryland, and Gibbons v. Ogden. However, rather than reducing tariffs, this period saw the approval of a protective tariff to support American manufacturing, raise revenue for the government, and decrease dependence on foreign trade, indicating that 'd' is the correct answer as it does not represent an evidence of post-War of 1812 American nationalism.
