Under what circumstances would the protest of the students in Tinker v. Des Moines be deemed unprotected speech?

In Tinker v. Des Moines, students’ symbolic speech was protected because it did not substantially disrupt school or interfere with others’ rights. If their protest had clearly threatened order and safety, the school could restrict it as disruptive or dangerous. Supporting an unpopular opinion alone would not remove First Amendment protection, so A is correct.
