The correct answer is the "supremacy" clause. This clause of the Constitution, specifically found in Article VI, Clause 2, establishes that the Constitution, federal laws, and treaties are the supreme law of the land. This means that in cases where state laws or constitutions conflict with federal laws or the Constitution itself, the Supreme Court has the authority to rule in favor of the federal laws, ensuring their supremacy.
Here's a breakdown of the options given:
1. Necessary and Proper Clause: Also known as the "Elastic Clause," this grants Congress the power to pass laws deemed necessary and proper to carry out its enumerated powers. It is not directly related to the Supreme Court's authority over state laws.
2. Supremacy Clause: As explained above, this clause establishes the superiority of federal law over state law in case of a conflict.
3. Commerce Clause: This clause gives Congress the power to regulate commerce among the states and with foreign nations. While the interpretation of this clause has been a source of debate, it does not specifically address the Supreme Court's authority over state laws.
4. Elastic: This term is sometimes used to refer to the Necessary and Proper Clause due to its flexibility in allowing Congress to pass laws needed to execute its powers. It is not the specific clause that grants the Supreme Court authority over state laws.
