Which amendment provides freedom of religion?

3rd amendment

8th amendment

9th amendment

1st amendment

The 1st Amendment

Explanation:

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

That would be the 1st amendment because it declares freedom of speech, assembly, and press.
