Which clause states that federal law overrides state law when there is a conflict?

• A. Elastic Clause
• B. Supremacy Clause
• C. Commerce Clause
• D. Due Process Clause

Answer: (B)

The principle being tested is that federal law wins over state law when they conflict. This is established by the Supremacy Clause, which says that the Constitution and federal laws are the supreme law of the land. When a state statute clashes with a federal statute or regulation, the federal rule preempts the state rule to the extent of the conflict, ensuring national consistency in areas under federal power.

The other clauses don’t express this hierarchy. The Elastic Clause expands Congressional power to pass laws necessary and proper to carry out its duties; it isn’t about resolving conflicts between state and federal laws. The Commerce Clause authorizes federal regulation of interstate commerce, but it’s a source of federal power, not a statement about supremacy. The Due Process Clauses protect fair treatment and fundamental rights, not the overriding of state laws by federal law.
