D. Both A and C Because the land is rising faster than sea level, stormdamage and erosion along emergent coastlines are relatively unimportant. This submerged bar of sediment allows longshore drift or littoral drift to continue to transport sediment in the direction the waves are breaking, forming an above-water spit.
