Which amendment protects the freedom of religion?

The First Amendment of the United States Constitution is significant because it explicitly protects several fundamental rights, including the freedom of religion. It states that Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof. This dual provision ensures that individuals can practice their religion freely without government interference, as well as preventing the government from establishing an official religion or favoring one religion over another.

The other amendments listed do not address the issue of religious freedom. The Second Amendment focuses on the right to bear arms, while the Fourth Amendment relates to protection against unreasonable searches and seizures. The Fifth Amendment primarily deals with rights related to legal proceedings, such as protection against self-incrimination and ensuring due process. Therefore, the First Amendment is the correct choice for the protection of religious freedom.
