The rhetorical appeal of logos relies on the logic and reasoning the speaker’s credibility the recipient’s emotions the tragic heroine’s flaw

The logic and reasoning.

Explanation:

Logos, in Greek philosophy, refers to the concept of reason. In the context of speech and arguments, it is often contrasted with two other concepts - ethos and pathos. Together, the three terms are known as Aristotle's rhetorical appeals or mode of persuasion - basically, how to convince an audience based on what type of argument you would like to use.

When using logos to convince an audience, you are appealing to their reasoning by making arguments that are coherent and logical. Credibility and emotions are instead appeals based on ethos and pathos, respectively.
