B. rock and metals; volatiles

Explanation:

  • According to the structure of the planet they are divided into terrestrial and Jovian. Terrestrial planets have a solid, rocky surface, are relatively high densities, slow to rotate, lack a ring, and have little or no satellites.
  • They include all inland planets: Mercury, Earth and Mars. Of these Venus, Earth and Mars have atmosphere, while Mercury is practically gone. It is so thin that we cannot speak of it in our earthly sense.
