Foliation in metamorphic rocks is due to directed stress,which causes elongated minerals to orient themselves
A)in parallel planes with the face of each plane parallel to the direction of maximum stress.
B)in alignment.
C)so that smaller crystals precede larger crystals.
D)in parallel planes perpendicular to the direction of maximum stress.
