Explanation:

The correct answer is "It said that the planets and the Sun revolve around Earth."

Explanation:

Ptolemy created a geocentric model with the earth in the center of the universe and all the planets describing epicycles around it. An epicycle is a circle orbit that was supposed to be described by a planet around a center that moved in another major circle (called a deferential), on which said center of rotation moves. Then, Ptolemy's theory basically proposed that each planet was animated by a double movement: one around the Earth in a large circle, called a deferential, and one around a moving point on the deferential itself, called the epicycle.

The planets sweep equal areas at equal times, and the epicycles and deferents cannot explain it. Ptolemy introduced the definition of "equating", a point outside the Earth on which the deferer rotates with uniform circular motion, that is to say at constant speed.

With the arrival of Copernicus, it was changed to a similar model but that proposed that the Earth and the planets revolve around the sun.

So the correct answer is "It said that the planets and the Sun revolve around Earth."
