Answer:
C) Ethos
Step-by-step explanation:
Ethos is a mode of persuasion that uses or mentions a source or figure that shows credibility, expertise or prestige in order to convince an audience that the information given is reliable, valid, or worth listening.
The lines provided are an example of that rhetorical appeal. Jefferson uses ethos when he establishes the source of the representatives’ authority: "the good People of these Colonies", in order to show that the Declaration of Independence comes from the ideas of good people, and therefore, its content is valid and something that is worth paying attention to.
