A) West Virginia State Board of Education v. Barnette (1943) CORRECT This case directly involved the Free Exercise Clause. The Supreme Court ruled that compelling students to salute the flag and recite the Pledge of Allegiance violated their religious beliefs, specifically those of Jehovah's Witnesses. The decision reinforced that the government cannot force individuals to engage in symbolic speech that contradicts their faith, establishing a strong precedent for protecting religious liberty in public schools.
B) McCulloch v. Maryland (1819) INCORRECT This case dealt with the Necessary and Proper Clause and the Supremacy Clause, not religious freedom. The Supreme Court upheld the constitutionality of the Second Bank of the United States and ruled that Maryland could not tax a federal institution. It established the principle of implied powers and federal supremacy, but it has no bearing on the Free Exercise Clause.
C) Marbury v. Madison (1803) INCORRECT This landmark case established the principle of judicial review, allowing the Supreme Court to declare laws unconstitutional. It arose from a political dispute over a judicial appointment and did not involve religious freedom. While it is a foundational case in American constitutional law, it is unrelated to the Free Exercise Clause.
D) Plessy v. Ferguson (1896) INCORRECT This case upheld racial segregation under the 'separate but equal' doctrine, which was later overturned by Brown v. Board of Education. It concerned the Equal Protection Clause of the Fourteenth Amendment, not religious freedom. The case is significant in civil rights history but does not involve the Free Exercise Clause.
