Answer:
Option A.
Step-by-step explanation:
Made illegal any public expression opposing the war, is the right answer.
Enacted in the year 1918, the Sabotage Act was an act that expanded the definition of the Espionage Act. This act made it illegal to express opposition to the war publicly and made provisions to prosecute anyone who criticizes the policies implemented by the president or administration.
Similarly, the Sedition Act made it a federal crime to employ "disloyal, temporal, abusive language or scurrilous" regarding the Constitution, the presidency, the uniform of Americans, or the flag of the United States.
Therefore, both the acts made it illegal to express opposition to the war publicly.
