The correct answer is A. National Labor Relations Act.
The National Labor Relations Act, passed in 1935, is a federal law that gave private sector employees significant rights in the work place. These rights include the ability to join a union without penalty, the ability to collectively bargain with their employers over wages, and the opportunity to take collective action (like striking) against their employers if the conditions/wages are not up to par. This was history in the making, as laborers had been fighting for legal rights like this since the late 19th century.
The public school students' <em>silent</em> protest, by using <em>symbols</em>, in the form of armbands, during school time, cost the students a suspension, because it was considered a <em>violation of a school rule</em>. After the case had been judged by the Supreme Court, they finally won the case. But the outcome could be different, if their protest used "indecent speech" or promoted illegal drug use.
