The correct answer is B.
The Sedition Act of 1918 extended the Espionage Act of 1917, covering a broader range of offences they were also prohibited since its enactment, mostly those which were positioned against the goverment or the war effort.
During WWI, twosocialists, Charles Schenck and Elizabeth Baer handed out fliers in which they stated that the draft was violating the Thirteenth Amendment by obliging citizens to go to war against their will, or in other words, to oblige them to involuntary servitude.
The Supreme Court decided that the Espionage and Sedition Acts should be enforced and that in this Schenck v. United States case, obstructing the draft was considered a criminal offence.
