Final answer:
The correct answer to the question is d) Hemostasis, which is the phase of wound healing where fibrin is deposited and clotting begins with the formation of a blood clot.
Step-by-step explanation:
In the hemostasis phase of wound healing, fibrin is deposited at the site and clotting begins. Therefore, the correct answer to the student's question is d) Hemostasis. During this phase, a blood clot is formed to stop bleeding. This process involves three steps that include vascular spasm, the formation of a platelet plug, and finally coagulation.
It is during the coagulation step that fibrinogen is converted to fibrin, which creates a mesh that traps more platelets and erythrocytes, thereby producing a clot. This phase prevents further blood loss and stabilizes the injury site for the subsequent phases of healing.
