Arrange the following steps of the Solar System's formation in the correct order: A) Ice chunks from the outer regions began to coalesce into larger bodies, B) A flat disk of material formed around the young Sun, C) Inner planets developed as rocky bodies in the warmer region, D) Gravity from the larger outer planets began to influence the distribution of comets.

The first step is the formation of a flat disk of gas and dust around the newborn Sun (B). From that disk, material in the warmer inner region collapsed into rocky planets (C). Farther out, where temperatures were low, ice-rich chunks began to stick together, forming the seeds of outer planets and comets (A). Finally, as the outer planets grew, their gravity reshaped the paths of comets and other icy bodies, pulling them into new orbits (D). This sequence explains how the Sun, planets, and cometary belts came into being.
