A. Democracy.

Explanation:

The age of Enlightenment of the 17th and 18th centuries was an age of ideas intellectually and philosophically where reason centers the basics of everything. Thinkers of this period began to question traditional authority and chose to propagate the idea of humanity through rational changes.

Philosophers of this Enlightenment believe in the notion of a democratic government where the people can have their voices heard and also participate and be a part of the government system. With the decline in the monarchical ruling system, democracy began to emerge as the popular form of governing the people, in the belief that the government is created for the people and their welfare, and thus, it is only reasonable that they are made a part of the system. Famous thinkers of this age include Thomas Hobbes, John Locke, Jean-Jacques Rousseau, René Descartes among others.
