You forgot to include the options for this question. However, we can answer the following.
The principle of government that is expressed in the excerpt from the Declaration of Independence is the principle of Republicanism.
The excerpt of the Declaration says: "In every stage of these Oppressions, We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury."
So the correct principle is Republicanism, the form of government in which the citizens are protected by the law. These citizens can participate and make decisions through their representatives because, in a Republic, politics is a public thing that involves the participation of citizens.
