The correct answer is A) dissenters.
During World War I, the federal government placed the greatest legal restrictions on dissenters.
Dissenters opposed World War I. They did not want to enlist in the Army to go to war. If they were caught, they were sent to war. Among the people who opposed war were pacifists, radicals, members of the clergy, feminist, liberal professors, and liberal publishers. These people expressed antiwar dissent.
