The third choice, different types of artifacts
The correct answer is B.
The Schenk case dealt with Schenk encouraging people to avoid the military draft during World War I. He was arrested but argued that his first amendment freedom of speech was violated. After making its way through state and local courts, the case made it all the way to the Supreme Court. However, the court ruled it was NOT protected by the first amendment right of freedom of speech. This is because it caused a clear danger to the US war effort, which could cause the US to lose World War I.
The answer is the last choice, commonality.
