A

B is the correct answer. Edwards v. South Carolina is significant because it limited states’ ability to restrict the freedom of speech.

Explanation:

The case was directly related to a breach of the United States’ first amendment that guarantees freedom of speech. In 1963, the protest of black students for their civil rights initiated the case. When the State of South Carolina arrested them for demanding an end to segregation, lynching, and other forms of discrimination, it created a precedent for the violation of the first amendment. The case defended the freedom of speech and assembly on a federal level.

The results of the court had the opposite effect on the protection of protestors, granting them increased rights. Additionally, the case was not in any way related to the conviction of criminals (Answer C) or freedom of the press, such as the New York Times (Answer D).
