Answer B is the closest to the truth. I do not like the term “empire,” though because that suggests rule by an emperor. I would submit that the country is not ruled by an emperor, but instead by two political parties that have conned the public into blindly voting for them in spite of the past several decades’ worth of evidence of their incompetence. So, while in a Republic, we’re governed by our elected representatives, in our current system, we’re governed by the leaders of the Democrat and Republican parties.
