The correct response is:
B If the speech creates a danger to the United States it is not allowed.
In the majority opinion of Schenck v. United States (1919), Justice Oliver Wendell Holmes, Jr. articulated the "clear and present danger" test, which establishes that speech is not protected under the First Amendment if it poses a significant risk of leading to harm that Congress has the right to prevent. In this case, Schenck's speech was deemed to create a clear and present danger of obstructing the draft during World War I.
