c. American exceptionalism.

Explanation:

Based on the concept of American exceptionalism, America is different, exclusive, and serves as an example for other nations while also being the exception, because it developed differently from them legislatively speaking. This conception is based on the presence and absence of some elements that distincts the U.S. from other countries. The abscence of feudalism, clashes of interests between classes, socialism in labor parties, trade unions, and ideas that divide people, and the presence of a leading middle class, acceptance for different cultures, a spirit of progress, and cordiality for immigrants, among other things, are what distinct America from other cultures of the world.
