Respuesta :
The geocentric model represents the earth at the center of the universe. The model couldn't explain the backward and loop movement of the planets. Thus, option d is correct.
What is the geocentric model?
The geocentric model was an early cosmological theory given by Eudoxus and Aristotle that defined Earth at the center of the universe with planets and the Sun revolving around it. It stated about the circular path followed by the celestial bodies.
The people on the Earth do not feel the planet moving, and hence it was assumed that it was the center. The circle being perfect was considered to be the motion of the revolution.
The model cannot establish the backward and loop-like movement of planets like mars where they move ahead and a little back when revolving.
Therefore, option d. the backward movement of the planets did not support the geocentric model.
