Answer: A) students' rights to free speech
Explanation:
In 1965, Mary Beth Tinker, a 13-year-old high school student, <u>protested against the War in Vietnam by wearing a black armband. </u>
As a sanction, she was prohibited from wearing the armband by school officials and she also got a suspension, together with her brother and another student. When the students came back to school, they didn't wear armbands anymore, but they were dressed in black for the rest of the school year.
The case was brought before the court by the ACLU (American Civil Liberties Union). The Supreme Court ruled that students are allowed freedom of expression at school, provided that it doesn't damage the educational process.
