If the following events were placed in their most probable order of occurrence following a skin wound which would come fourth?

The answer is E. In a wound healing by first intention the gap fills with blood clot (A); epithelium migrates from the wound edges and within 48 hours the gap is bridged by epithelium (D); granulation tissue grows into the wound (B) forming a scaffolding by which the wound edges are united by collagen (D), producing a narrow fibrous scar which gradually loses its vascularity (C).
