Which clause in the Constitution establishes that federal law is the supreme law of the land?

• A. Commerce Clause
• B. Necessary and Proper Clause
• C. Supremacy Clause
• D. Due Process Clause

Answer: (C)

Federal law taking precedence over state law is established by the Supremacy Clause. This clause, in Article VI, Clause 2, says that the Constitution, laws made under it, and treaties are the supreme law of the land, and it binds judges in every state. Because of it, when a federal statute conflicts with a state law, the federal provision wins, ensuring a consistent legal framework across the country. The other options don’t set this relationship: the Commerce Clause regulates interstate trade, the Necessary and Proper Clause allows Congress to pass laws needed to carry out its powers, and the Due Process Clause protects individuals from unfair government actions.
