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

The phrase "We the People" serves as a powerful declaration of the principle of self-government in the United States. It underscores the idea that the authority of the government derives from the consent of the governed, meaning that the power ultimately rests with the citizens. This foundational statement sets the tone for the entire Constitution, indicating that the nation is built on the will and unity of its people, rather than being imposed by a monarch or external authority.

The other options, while significant, do not embody the concept of self-government in the same way. "In God We Trust" reflects a national motto, but it does not address the relationship between government and the people. "Of the People" is part of a longer phrase that conveys a similar sentiment but lacks the direct and concise declaration found in the first three words of the Constitution. "To Form a More Perfect Union" describes one of the purposes of the Constitution but does not convey the foundational principle of self-governance as succinctly as "We the People." Thus, the correct choice effectively emphasizes that the Constitution and government are meant to represent and serve the citizens of the nation.
