What are the first three words of the Constitution that express the idea of self-government?

The phrase "We the People" is significant as it embodies the principle of popular sovereignty, which is the foundation of American democracy. This opening clause of the Constitution emphasizes that the authority of the government is derived from the consent of the governed. It reflects the idea that the citizens, rather than a monarchy or external authority, are the primary source of political power. This concept implies that the government exists to serve the interests and rights of the people, reinforcing the notion of self-government where individuals have the right to determine their own governance. The other options either do not encapsulate this principle or suggest a focus on states or groups rather than the individual citizens themselves.
