What is the main purpose of the Constitution?

The main purpose of the Constitution is to establish the framework of the government and protect individual rights. This foundational document serves as the supreme law of the land, delineating the structure of the government, the separation of powers among the legislative, executive, and judicial branches, and the relationship between the federal government and the states. Additionally, the Constitution includes the Bill of Rights, which explicitly outlines the rights and freedoms of individuals, thereby safeguarding these rights from infringement by the government.

This comprehensive approach ensures not only that the government operates within set boundaries but also that the rights of citizens are prioritized and protected, thus creating a balanced system that promotes democracy and freedom. The other options do not address the broad and fundamental role of the Constitution in shaping the national government's structure and safeguarding personal liberties.
