Answer:
A. heliocentric
Step-by-step explanation:
The apparent movement of the sun across the sky and also with some other stars, moons and planets is a proof of the heliocentric model of the earth.
- In the heliocentric model, the sun is at the center of the solar system.
- The geocentric model pitches the earth as the center.
- It is the earth the moves round the sun and not the other way round.
- This gives the various times we have in a day.
