How Do the Moons of Jupiter Behave When Considered in Terms

Multiple Choice

How do the moons of Jupiter behave when considered in terms of the relationship between the period P and radius a of their orbits around the planet?

A) Jupiter's moons follow the Keplerian relationship P² = ka³, where k is a constant that is different from that in the relation governing planetary motion around the Sun.
B) Jupiter's moons do not obey the Keplerian relationship P² = ka³ because their motion about Jupiter is affected by Jupiter's motion about the Sun.
C) Jupiter's moons obey the Keplerian relationship P² = ka³ where k is the same as that for planetary motion around the Sun because it is a universal constant.
D) Jupiter's moons do not obey the Keplerian relationship P² = ka³ because they orbit Jupiter, not the Sun.
