Final answer:
Aristotle taught incorrectly that the Earth is at the center of the universe.
Step-by-step explanation:
Aristotle taught incorrectly that the Earth is at the center of the universe (option A).
Aristotle's geocentric model placed Earth as the stationary center of the universe, with the Moon, planets, the Sun, and the stars all revolving around it in complex superpositions of circular paths. It was only with the development of Copernican heliocentrism that the understanding of the true nature of the universe began to emerge.
For example, Copernicus proposed that the Sun is at the center of the solar system, and that the Earth and other planets revolve around it in elliptical orbits.
