Why did aristotle's geocentric theory fail to match the expected predictions?
a) all stars appear to move in different directions.
b) a few celestial objects appear to have retrograde motion.
c) all celestial objects periodically exhibit retrograde motion.
d) the sun's motion is erratic.

(idk what subject it is)

Aristotle's geocentric theory failed to match the expected predictions because a few celestial objects appear to have retrograde motion.

Option B

Explanation:

Aristotle’s theory states that all the bodies in universe rotate around the earth, and earth is located at the centre. But, the most serious challenge it was given was that, the difference found in the paths of revolution of mercury and Venus. They are revolving around the sun, and not the earth, periodically.

This is the significant drawback, and major factor for the Copernicus and the other models to be achieved. The mercury and Venus, closest planets to earth, and the sun too, are not following the earth’s path. And hence, upon studying clearly, all celestial bodies do not follow a path round the earth, but around a fireball, that is sun.
