Many meteorites appear to have formed very early in the solar system's history. How do these meteorites support the nebular theory's scenario for the formation of the terrestrial planets?
A) The appearance and composition of these meteorites is just what we'd expect if metal and rock condensed and accreted as the nebular theory suggests. B) The sizes of these meteorites are just what we'd expect if metal and rock condensed and accreted as the nebular theory suggests. C) The overall composition of these meteorites is just what we believe the composition of the solar nebula to have been: mostly hydrogen and helium. D) The appearance and composition of these meteorites matches what we observe in comets today, suggesting that they were once pieces of icy planetesimals.
