Which clause states that federal law is the supreme law of the land, binding on the states regardless of state laws?

• A. Article I, Section 8
• B. Due Process Clause
• C. Full Faith and Credit Clause
• D. Supremacy Clause

Answer: (D)

The Supremacy Clause establishes that federal law is the highest law in the land and binds the states even when a state has a conflicting law. Found in Article VI, Clause 2 of the Constitution, it means that if a federal statute or constitutional provision conflicts with a state law, the federal provision controls and the state law must give way.

This isn’t about Congress’s enumerated powers, which is what Article I, Section 8 outlines, nor about fair procedures guaranteed by the Due Process Clause or about states recognizing each other’s acts under the Full Faith and Credit Clause. Those other provisions serve different purposes, while the key idea here is federal law’s primacy over state laws.
