D. Metamorphic

Metamorphic rocks can have the largest range of densities among the rock groups. This is because metamorphic rocks are formed from the transformation of existing rock types (which can be igneous, sedimentary, or other metamorphic rocks) under high pressure and temperature. The process of metamorphism can cause significant changes in the mineral composition and structure of the rocks, leading to a wide range of possible densities. For example, a metamorphic rock could be as light as a shale (which can have a density as low as 2.2 grams per cubic centimeter) or as dense as an eclogite (which can have a density as high as 3.5 grams per cubic centimeter).
