C. The pancreas secreting insulin to regulate blood sugar.

Explanation: Negative feedback reduces a deviation from a set point — high blood glucose triggers insulin release, which lowers blood glucose back toward normal, then insulin secretion decreases. Blood clotting and childbirth are examples of positive feedback (they amplify the response), and itching from an allergic reaction is not a homeostatic negative-feedback mechanism.
