Ineed an answer asap. which is not a reason for the “era of good feeling”? a) economy in the us was booming. b) the united states was victorious in the war of 1812. c) the united states outlawed slavery. d) the federalist party was disbanded and the united states had one political party.

The correct answer is C) The United States outlawed slavery.

The "Era of Good Feelings"refers to the era of the Monroe Presidency which took place from 1817-1825. However, the United States is not going to outlaw the institution of slavery until the passing of the 13th amendment.

letter d is correct.
