Aristotle a. wrote works praising one of the other philosophers who left no writings b. taught by asking questions c. analyzed how people used and could use logic

The correct option is C

Aristotle was a philosopher, polymath and scientist born in the city of Estagira, north of Ancient Greece. He is considered next to Plato, the father of Western philosophy. His ideas have exerted an enormous influence on the intellectual history of the West for more than two millennia.

Aristotle wrote about 200 treatises (of which only 31 have survived) on an enormous variety of subjects, among them: logic, metaphysics, philosophy of science, ethics, political philosophy, aesthetics, rhetoric, physics, astronomy and biology. Aristotle transformed many, if not all, of the areas of knowledge he addressed. He is recognized as the founding father of logic and biology, because although there are reflections and previous writings on both subjects, it is in the work of Aristotle, where the first systematic investigations on the subject are found.
