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

The First Amendment of the United States Constitution is primarily concerned with protecting various forms of freedom concerning expression and belief. Among these protections is the freedom of religion, which encompasses both the right to practice one's religion freely and the establishment clause, which prohibits the government from establishing an official religion or unduly favoring one religion over another.

This amendment ensures individuals can express their religious beliefs without government interference, reflecting the foundational principle of religious liberty in the United States. The other options, while important rights, fall under different amendments: the right to bear arms is protected by the Second Amendment, the right to a fair trial is addressed in the Sixth Amendment, and protection against double jeopardy is outlined in the Fifth Amendment. Understanding the specific amendments associated with various rights is critical in grasping the broader constitutional framework governing individual freedoms in the United States.
