The planets all lie in nearly the same plane,resulting in a disk-like structure for the solar system.What is believed to be the reason for this disk-like structure?
A)The solar nebula from which the planets formed collapsed into a disk-like structure.
B)The bipolar flow from the young Sun cleared all material out of the nebula except the material in the disk.
C)Jupiter's gravity was great enough to pull all of the other planets to the plane of its orbit.
D)The Milky Way galaxy from which the planets condensed has a disk-like structure.

The most accepted explanation for the disk-like structure of the solar system is that it resulted from the solar nebula collapsing into a disk-like structure. The solar nebula was a cloud of gas and dust that collapsed due to gravitational forces and formed the Sun and the planets. As the cloud rotated, it flattened into a disk-like structure due to conservation of angular momentum. This disk-like structure then led to the formation of the planets, which all orbit in nearly the same plane.
