Explanation:

• Option A: The geocentric model, historically, posits Earth as the center of the universe, with celestial bodies orbiting around it. This is a core characteristic of the geocentric model.
• Option B: The geocentric model was replaced by the heliocentric model (which places the Sun at the center), not the other way around. So B is incorrect.
• Option C: The geocentric model was developed based on the apparent motion of the Sun, stars, and other celestial objects as observed from Earth (e.g., the Sun appears to rise and set, move across the sky), so this is a valid basis for the model.

Answer:

A. It shows Earth as the center of the universe.
C. It was based on the apparent motion of the sun and stars.
