The correct answer is C). No, because schools could search students belongings only if there is a reasonable suspicion of wrongdoing.
The case referred is New Jersey v. T.L.O. in 1985.
T.L.O. was a 14-year-old female student at a New Jersey high school, when a teacher found her smoking cigarettes with another girl in the restroom, violating school rules.
The U.S. Supreme Court conclusion was that, under the circumstances of the case, the search of T.L.O.’s backpack did not violate the Fourth Amendment to the United States Constitution. However, the Court did not address if unlawfully seized evidence should be suppressed in a juvenile delinquency hearing. Nevertheless, the Court decided that the Fourth Amendment applies to school officials.
