What does the Constitution do?

The Constitution serves as the foundational legal document of the United States, establishing the framework for the government and delineating the roles and responsibilities of its various branches. It also specifies the relationship between the federal government and the states while outlining essential rights and freedoms guaranteed to individuals. This dual role is crucial, as it not only organizes the structure of governance—such as the legislative, executive, and judicial branches—but also includes the Bill of Rights, which explicitly protects citizens' fundamental rights, such as freedom of speech and religion.

The other options do not accurately capture the primary functions of the Constitution. While the Constitution has implications for international relations, it does not specifically provide a framework for that aspect. Additionally, outlining the rights of states is just one part of the broader framework established by the Constitution and is not its primary function. The Constitution deliberately limits government power rather than granting it unlimited authority, ensuring checks and balances to protect citizens from tyranny. Thus, the correct choice encapsulates the comprehensive role of the Constitution in American society.
