What is a constitution?

A constitution is fundamentally a set of principles and rules that outlines the governance of an organization, such as a nation or state. It establishes the framework for government structure, delineates the powers and responsibilities of various branches, and ensures the rights of individuals within that governmental system. This guiding document serves as the highest law of the land, providing a basis for creating laws, implementing policies, and resolving disputes.

This option accurately encapsulates the essence of what a constitution represents in both historical and contemporary contexts, highlighting its role in maintaining order and protecting the rights of citizens. Other choices do not reflect the established function and purpose of a constitution: economic policy legislation focuses specifically on finance and trade, military strategies pertain to defense plans rather than governance, and declarations of independence are proclamations about sovereignty rather than foundational governance documents.
