Which observation most strongly supports the conclusion that mechanical stress alone can reorganize mineral structure in solid rock without melting?
A
The coarse crystalline substrate displays alternating mineral zones that resulted from the combined effects of heat and compression.B
The fine-layered sediment substrate shows planar mineral bands produced under direct pressure without the aid of heat or fluids.C
The carbonate-rich substrate developed a mosaic of interlocking crystals after mild heating and limited fluid flow.D
The volcanic substrate contains metallic veins formed as circulating fluids deposited new minerals in open spaces.
