Which of the following is an example of a right that is protected by the First Amendment?

Serving on a trial jury is a civic duty and not a right protected by the First Amendment. It falls under procedural rights within the justice system, specifically related to the Sixth and Seventh Amendments, which guarantee the right to a fair trial and jury.

Carrying a concealed weapon relates more directly to the Second Amendment, which addresses the right to bear arms. While there are discussions regarding the limits of this right, it does not fall under First Amendment protections, which focus on freedom of speech, religion, press, assembly, and petition.

Making a citizen's arrest is not a right protected by the First Amendment. It involves law enforcement powers that are regulated by state laws and is not related to the freedoms of expression, religion, or assembly that the First Amendment safeguards.

Remaining silent during police questioning relates to the Fifth Amendment, which protects against self-incrimination, rather than the First Amendment. While it is a constitutional right, it does not fall under the protections of free speech or expression.
