D. Adopting an animal will not only save the animal's life, but it will also bring you love and joy
Explanation:
Pathos is a mode of persuasion that aims to convince someone on something by appealing to their emotions. This tool of persuasion is characterized for not expressing statistic elements or facts that support the speaker's claim, but, instead, for being highly subjective and to evoke strong emotions. Sentence D, then, uses pathos because it appeals to people's joy, compassion, and love in order to convince them of adopting an animal.
I would say D. because all of the others are basically answering the entirety of the speech. If you would discuss ways to increase the literacy rates in the U.S. you would need to go over it last after you explain why the U.S. is so illiterate.
