A) the overriding plate is either not moving toward the subducted slab relative to the asthenosphere, or it is moving away
B) the overriding plate is moving toward the subducted slab relative to the asthenosphere
C) no magma is created by the subduction process
D) an accretionary prism has developed at the convergent plate boundary
