What is planetary migration, and how may it account for the surprising orbits of many extrasolar planets?

A) Many extrasolar planets are much closer to their stars than we had expected. In fact, our formation model does not allow jovian planets to form that close to their stars. However, we think that it is possible for planets to migrate through their disks because of interactions with the gas in the disk.
B) Many extrasolar planets are much closer to their stars than we had expected. Our formation model allows jovian planets to form that close to their stars. However, we think that it is also possible for planets to migrate through their disks because of interactions with the gas in the disk and so we find many more jovian planets close to the stars than we expected.
C) Many extrasolar planets are much farther from their stars than we had expected. In fact, our formation model does not allow jovian planets to form that far from their stars. However, we think that it is possible for planets to migrate through their disks because of interactions with the gas in the disk.
D) Many extrasolar planets are much farther from their stars than we had expected. Our formation model allows jovian planets to form this far from their stars. However, we think that it is also possible for planets to migrate through their disks because of interactions with the gas in the disk and so we find many more jovian planets far from the stars than we expected.

Answer : B) Many extrasolar planets are much closer to their stars than we had expected. Our formation model allows jovian planets to form that close to their stars. However, we think that it is also possible for planets to migrate through their disks because of interactions with the gas in the disk and so we find many more jovian planets close to the stars than we expected.

Explanation : Migration means the planet gradually moves closer to its parent star. Many extrasolar planets are much closer to their stars than we had expected. We think that it is possible for planets to migrate through their disks because of interactions with the gas in the disk. Migration can lead to resonances, which can make orbits elliptical.
