While writing a persuasive piece, which appeal should you use to evoke emotion in your audience?

The answer is indeed pathos.

Explanation:

The three modes of persuasion or rhetorical appeals were described by Aristotle in his treatise Rhetoric. Those appeals are ways and means which a writer, a speaker, or even an advertiser can use to convince the audience of a point of view. The three modes of persuasion are ethos, logos, and pathos.

Pathos is the rhetorical appeal the evokes emotion in the audience. It targets shared feelings and cultural values with the goal of having the listener relate to what is being said. Pathos may be used to inspire pity, happiness, or anger, for instance. The purpose is to convince the audience of the speaker's opinion by having them feel a certain way. For example, it is easier to convince someone to donate money to your cause if you can get to them to feel sympathy for those you aim to help. By evoking such feeling in your audience, chances are that they will contribute.
