B. Positive feedback
Explanation:
The positive feedback or positive feedback mechanism occurs in smaller quantities compared to the negative feedback mechanism. Positive feedback, unlike negative feedback, ensures increased stimulus that causes imbalance, reinforcing it. Thus, positive feedback is not always beneficial, triggering, in some cases, detrimental effects on the body.
Although less than negative, positive feedback also plays an important role in our bodies. An example of this occurs when platelet release chemicals are activated in an injured tissue to attract more platelets, eventually forming a blood clot.
