The correct statement is: The establishment clause stops the government from favoring a religion while the free exercise clause allows people to express their religion.
To elaborate, the Establishment Clause, found in the First Amendment of the U.S. Constitution, prohibits the government from establishing an official religion or unduly favoring one religion over another. In contrast, the Free Exercise Clause protects individuals' rights to practice their religion freely without government interference, as long as their practices do not violate public morals or a compelling government interest.
