Suppose One Tries to Explain Rømer's Measurements in the Ptolemaic

Multiple Choice

Suppose one tries to explain Rømer's measurements in the Ptolemaic model (adding the Galilean moons) with circular orbits and Earth in the center of the system. How could the differences in eclipse times be explained?

A) The later times would still occur when Jupiter is at conjunction and the earlier times when Jupiter is at opposition.
B) The later times would occur when Jupiter is moving westward with respect to the stars and the earlier times when Jupiter is moving eastward with respect to the stars.
C) The later times would occur when Jupiter is moving eastward with respect to the stars and the earlier times when Jupiter is moving westward with respect to the stars.
D) Jupiter in this model is the same distance from Earth at all times so no explanation is possible.
