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

The correct answer is B because meteorites' appearance and composition matching the expected results of metal and rock condensing and accreting supports the theory of how terrestrial planets formed. This evidence aligns with the hypothesis that planets formed through the accumulation of smaller particles and objects in the early solar system.
