Final answer:
Terrestrial planets contain relatively little material in a gaseous state compared to gas giants or ice giants, being mostly composed of rocks and metals with thin atmospheres.
Step-by-step explanation:
The bodies that contain relatively little material in a gaseous state, given the options, are c) Terrestrial planets. Terrestrial planets, such as Earth, Venus, Mars, and Mercury, are predominantly rocky in nature. Unlike gas giants or ice giants, which have substantial gaseous envelopes and are much larger, terrestrial planets have dense, rocky surfaces and metal cores. The terrestrial planets were once molten, allowing for differentiation where denser materials sank to the center. These planets have a chemistry dominated by oxidized materials, mainly silicates and iron, and have relatively thin atmospheres compared to their giant counterparts.
