The correct answer is letter D
The republicanism that we associate with Machiavelli has as its starting point the praise of the action and the participation of citizens in the public arena. In a world in which no recipe for what to do to create a better future has universal validity, men cannot help acting if they do not want to be engulfed by the chaotic set of forces that intervene in history. It is not a matter of defending the virtue of citizens as an abstract good, but of showing the role of participation in a territory that is not entirely dominated by the fixed laws of history, nor by blind market forces.
Another decisive aspect for thinking about Machiavelli's republicanism is the role attributed to the conflicts and divisions of the political body. Against a long tradition of Western thought, he did not see unity as the main objective of the common life of men, since the desire to achieve it can lead to the destruction of freedom. A free regime is one capable of accommodating disputes and differences between its citizens in its institutions and not an unrealizable dream of perfection and harmony among all.
