Which of the following rights is protected under the First Amendment?

The First Amendment of the United States Constitution is primarily concerned with protecting individual liberties related to expression and religion. It guarantees several fundamental rights, among which freedom of speech holds a prominent position. This means individuals have the right to express their opinions and information without government interference, fostering open discourse and the exchange of ideas, which are essential for a democratic society.

The other options refer to rights that are protected under different amendments. For example, the right to bear arms is protected by the Second Amendment, the right to a fair trial is guaranteed by various provisions in the Sixth Amendment, and the right to vote is generally protected under the Voting Rights Act and the Fifteenth, Nineteenth, and Twenty-fourth Amendments, among others. However, none of these other rights are explicitly enumerated within the First Amendment, making freedom of speech the clear answer here.
