Answer:
C. The First Amendment protects the students' rights to wear the armbands ; they weren't disruptive, and the school allowed other students to wear controversial symbols.
Step-by-step explanation:
In the Supreme Court, the majority of the Justices (7-2) determined that public schools could not prohibit the wearing of armbands in the school, as a form of symbolic protest that did not disrupt the peace and order in the institution, because it constituted a violation to the students' freedom of speech right guaranteed by the First Amendment to the U.S. Constitution.
