The BEST explanation for the formation of a metamorphic rock from a 5000 kg igneous rock under extreme heat and pressure would be:
**D The new metamorphic rock would have the approximate same mass as the igneous rock.**
When metamorphic rock forms from pre-existing rock (whether igneous, sedimentary, or other metamorphic rocks), the mass is generally conserved. While the mineral composition and texture may change due to the conditions of heat and pressure, the overall mass of the rock would remain approximately the same, barring any significant material loss (which is typically minimal).
