The rock in Diagram A seems to not have that much stress on it, the one in B seems to be pushing itself together, the one in C seems to be pulling itself apart and the one in D seems to be sliding past each other. A has not had any stress as its staying still while B seems to be a tectonic plate where subduction is occurring, in rock C it also seems to be a tectonic plate where it is a Convergent Boundary, rock C seems to be a Divergent Boundary and D seems to be a Transform Boundary.
