The correct option is
A Aristotle
Aristotle was an ancient Greek philosopher and scientist, one of the greatest intellectual figures of Western history. He was the author of a philosophical and scientific system that became the framework and vehicle for both Christian Scholasticism and medieval Islamic philosophy. Even after the intellectual revolutions of the Renaissance, the Reformation, and the Enlightenment, Aristotelian concepts remained embedded in Western thinking.Aristotle’s intellectual range was vast, covering most of the sciences and many of the arts, including biology, botany, chemistry, ethics, history, logic, zoology, etc. He was the founder of formal logic, devising for it a finished system that for centuries was regarded as the sum of the discipline; and he pioneered the study of zoology, both observational and theoretical, in which some of his work remained unsurpassed until the 19th century. But he is, of course, most outstanding as a philosopher. His writings in ethics and political theory as well as in metaphysics and the philosophy of science continue to be studied, and his work remains a powerful current in contemporary philosophical debate. Aristotle was born on the Chalcidice peninsula of Macedonia, in northern Greece. After his father’s death in 367, Aristotle migrated to Athens, where he joined the Academy of Plato (c. 428–c. 348 BCE). He remained there for 20 years as Plato’s pupil and colleague.
So the correct option is 'Aristotle'.
