The correct answer is C) Enlightenment
The Enlightenment period took place during the 18th century in Europe. This era saw a drastic change in the way that citizens viewed the purpose of government. This helped to spark the declaration of independence and social contract theory.
The Declaration of Independence contained Enlightenment ideas like the right of the governed. In the Declaration of Independence it discusses how any time a government becomes ineffective, the people have the right to replace it. This is an Enlightenment idea.
The social contract theory states that the power of the government comes from the citizens. This was also an Enlightenment concept.
