What does the Constitution do?

The Constitution serves as the foundational legal document that outlines the structure and functions of the government of the United States. It establishes the roles and responsibilities of the three branches of government: the legislative, executive, and judicial branches, ensuring a system of checks and balances among them. This setup is crucial for maintaining a democratic governance system where power is distributed rather than concentrated.

Moreover, the Constitution defines the relationship between the federal government and the states, setting the parameters within which state laws must operate. It also includes provisions for amending the Constitution, demonstrating its adaptability over time.

In contrast to the other options, the Constitution does not establish a monarchy, nor does it provide a religious framework or limit the powers of states as its primary function. Its main purpose is to lay down the structure of government and articulate the rights of the citizens, serving as the supreme law of the land.
