What major difference distinguishes the Constitution from the Declaration of Independence?

The Constitution is fundamentally different from the Declaration of Independence because it serves as a charter of government. The Constitution outlines the framework for the U.S. government, detailing the organization of the government, the separation of powers, the roles and responsibilities of its branches, and the rights of the individual. It establishes how laws are made and how power is distributed, ensuring a system of checks and balances among the legislative, executive, and judicial branches.

In contrast, the Declaration of Independence focuses on justifying the colonies' separation from Britain and lists grievances against King George III. It declares the colonies' intention to become free and independent states rather than providing a structure for governance.

The other options highlight aspects that do not accurately reflect the distinguishing features of the two documents, such as the signing dates and purposes that do not align with the role the Constitution plays in establishing government authority.
