Which First Amendment clause prohibits Congress from prohibiting the free exercise of religion?

• A. Free Exercise Clause
• B. Establishment Clause
• C. Lemon Test
• D. Due Process Clause

Answer: (A)

The main idea here is that the First Amendment contains a protection specifically about religious practice. The Free Exercise Clause says the government cannot prohibit or unduly burden an individual’s religious exercise. So, when the question asks which clause prohibits Congress from prohibiting the free exercise of religion, this clause is the one that directly addresses that power.

Understanding the contrast helps, too. The Establishment Clause bars the government from establishing an official religion or showing favoritism toward religion in general. The Lemon Test is a test developed to evaluate Establishment Clause concerns, not a constitutional clause itself. The Due Process Clause protects a broad range of fundamental rights and, through incorporation, applies some protections to the states, but it is not the specific prohibition on Congress regarding religious exercise.
