Answer: D
Explanation:
<em>Logos</em> appeals to the audience's logic/reason, <em>Ethos</em> appeals to the speaker's status or authority, making the audience more likely to trust them, and <em>Pathos</em> appeals to the emotions.
The best way to identify ethos is noticing which sentences come from credible sources or smart people. "I'm a doctor, and I can tell you this medicine is safe," something like that. D is the opinion of multiple professional zoologists, so we know it's ethos.
