The correct answer is b. Federalist supported the acts. Democratic-Republicans opposed them.
The Alien and Sedition Acts were a series of bills that were passed by the Federalist majority in the Congress between June and July of 1798.
This laws increased residency requirements, permitted the government to arrest and deport all male citizens of an enemy nation, allowed the president to deport any non-citizen suspected of plotting against the government, and also aimed at those who spoke out against Adams or the Federalist government.
