Which amendment guarantees freedom of religion?

The First Amendment to the United States Constitution guarantees freedom of religion. This amendment is a fundamental part of the Bill of Rights and ensures that individuals have the right to practice their religion without government interference. It prohibits Congress from establishing a national religion or prohibiting the free exercise of religion. This protection is seen as essential to a democratic society, allowing for a diversity of beliefs and practices.

Each of the other amendments listed addresses different rights; the Second Amendment focuses on the right to bear arms, the Third Amendment deals with the quartering of soldiers, and the Fourth Amendment protects against unreasonable searches and seizures. Thus, these amendments do not pertain to the protection of religious freedoms and highlight why the First Amendment is the correct choice for this question.
