Assuming that our ideas about how "hot Jupiters" ended up on their current orbits are correct, why didn't our own solar system end up with any hot Jupiters?
A. Our solar nebula must have been blown into space shortly after the formation of the jovian planets.
B. Our jovian planets must have migrated outward from inside the orbit of Mercury.
C. Our solar nebula must have stuck around for an unusually long time after the formation of jovian planets.
D. The existence of Earth and the other terrestrial planets prevented the jovian planets from migrating inward.
