The correct answer would be C. a feedback loop.
Feedback loop or mechanism is the process by which the concentration of a hormone is maintained in blood or extracellular fluids.
It works in a loop manner where product feeds back to control its own production.
It can be of two types:
- Positive feedback: In this, the product gives feedback to increase or elevate the production. For example, production of milk in mammary glands.
- Negative feedback: In this, the product gives feedback to decrease or inhibit production. For example, the hormones of thyroid glands.
