Democracy's superior virtue lies in the fact that it calls into activity
Explanation
Democracy's superior virtue lies in its reliance on popular sovereignty, where the active participation of ordinary citizens in the political process fosters their intellectual and moral development. While option (c) might seem plausible, it describes a "Great Man" theory or autocracy, whereas democracy specifically shifts focus away from elite individuals to the collective agency of the masses. The core concept being tested is the philosophical foundation of participatory democracy and the empowerment of the individual in a self-governing society.
