The correct answer is A) ethos, logos, and pathos.
Every argument should appeal to ethos, logos, and pathos.
Every time you address an audience yo have to convince them about your ideas. That is why pro speakers do. So you have a combination of elements that help you address the audience successfully.
Pathos is an emotional appeal. The speaker appeals to emotion in order to convince the audience. Logos is the logic, the rational appeal. You use arguments to convince the audience. And then, you have Ethos, the appeal to the image and reputation of the speaker.
