.
B. Heliocentric: This model is Sun centered. Retrograde motion is explained by the orbital speeds of planets

. Planets move in circular orbits and with uniform motion
. The brightness of a planet increases when the planet is closest to Earth.
Explanation:
The principle of the Ptolemy's geocentric model was developed on the assumption that the center of the universe is the Earth.
