The low average densities of the jovian planets, which have high masses and hence high gravitational fields, is an indication that their interiors are: A)gaseous and have not condensed to liquid or solid form. B)composed mainly of very light elements, such as H and He. C)composed of very porous rock (many small, empty cavities). D)composed of H₂O, CH₄ (methane), and NH₃ (ammonia).

The low average densities of the jovian planets, despite their high masses, indicate that their interiors are composed mainly of very light elements like hydrogen and helium, which have low densities. This composition makes them gaseous in nature and unlikely to have condensed into liquid or solid form. Therefore, option B is the best choice.
