A) Made from the same solar nebula, they are all similar.
B) More massive jovians all have high densities, compared to the tiny terrestrials.
C) All terrestrials are more dense than any of the jovians.

E) No real pattern here; densities vary greatly and are very individual to each world.

Question

Terrestrial planets are made up of heavy elements such as iron, nickel, and silicon, which result in high densities. On the other hand, jovian planets have much lighter elements like helium and hydrogen, which give them a lower density. Therefore, all terrestrials are more dense than any of the jovians.
