D. The remaining materials from the sun's formation clumped together due to gravity.
Explanation: After the Sun formed from a collapsing molecular cloud, the leftover gas and dust formed a rotating protoplanetary disk. Particles stuck together into planetesimals, which grew by accretion into protoplanets and finally planets. Inner planets are rocky (solid) while outer planets accreted large gas envelopes.
