What is the supreme law of the land?

The correct answer is the Constitution, which is recognized as the supreme law of the land in the United States. This designation means that the Constitution is the highest form of law in the country, and all laws or policies enacted by states and the federal government must comply with it. Article VI, Clause 2 of the Constitution, often referred to as the Supremacy Clause, explicitly establishes that the Constitution, along with federal laws and treaties made under its authority, take precedence over state laws.

The other options, while historically significant or foundational to American governance, do not hold the same legal authority. The Declaration of Independence is a pivotal document that announced the American colonies' separation from British rule and articulated the principles of individual rights and government. However, it does not serve as a governing document or law. The Bill of Rights, which comprises the first ten amendments to the Constitution, outlines specific protections for individual liberties but is part of the Constitution itself rather than an independent document that serves as the highest law. Lastly, the Articles of Confederation were the first governing document of the United States, but they were eventually replaced by the Constitution due to their inadequacies in unifying the states and providing a functional national government.
