To determine which religious practice is illegal based on the Supreme Court case Reynolds v. United States, it is necessary to understand the background of the case and its ruling.

In the case of Reynolds v. United States (1879), the Supreme Court dealt with the constitutionality of a law that prohibited polygamy. The defendant, George Reynolds, was a member of The Church of Jesus Christ of Latter-day Saints (Mormons) and had entered into a polygamous marriage, which was in violation of the law.

The Supreme Court, in a unanimous decision, held that religious duty was not a defense to a criminal indictment. The Court ruled that the Free Exercise Clause of the First Amendment does not protect practices that are deemed criminal or harmful. Consequently, polygamy was declared illegal, as it was considered a criminal act, regardless of any religious motivations or beliefs.

Therefore, the correct answer to your question is:
c. Polygamy

It is important to note that this answer is based on the specific Supreme Court case mentioned above. The legality of different religious practices may vary based on the specific context, court decisions, and evolving legal interpretations.
