What do we call all of the pros and cons along with the supporting evidence that the author presents to the audience to establish the truth of a given statement or the wisdom of a given recommendation?

A) a fruitless endeavor
B) the rhetorical situation
C) the existential heuristic
D) the author's case

The author's case refers to all of the pros and cons along with the supporting evidence that the author presents to the audience to establish the truth of a given statement or the wisdom of a given recommendation. A is incorrect because it suggests that the effort is pointless. B refers to the context and constraints that surround a communication, but doesn't specifically refer to the author's case. C is a made-up term that is not commonly used in communication studies.
