The correct answer is B) The use of symbolic speech in schools is protected by the First Amendment.
Tinker and her friends wore black armbands with the peace symbol on them to school as a means of peaceful protest against the US participation in the Vietnam War. Tinker was punished by the administration at her school for doing this. However, Tinker's family sued the school saying that her act did not disrupt the educational process and was protected by the first amendment. The Supreme Court sided with Dinker and expanded the rights of students in terms of free speech within schools.
