Answer: (C)

Verified step by step guidance

1. Understand the concept of feedback loops: Feedback loops are biological mechanisms whereby the body maintains homeostasis. They can be either positive or negative.
2. Identify the characteristics of a positive feedback loop: In a positive feedback loop, the response enhances or amplifies the initial stimulus, leading to an increased response.
3. Consider the process of uterine contractions during childbirth: During labor, uterine contractions push the baby towards the cervix, which in turn stimulates the release of oxytocin.
4. Analyze the role of oxytocin: Oxytocin further stimulates uterine contractions, creating a cycle that intensifies until childbirth is complete.
5. Conclude that uterine contractions during childbirth are an example of a positive feedback loop, as the process amplifies the initial stimulus (contractions) to achieve a specific outcome (childbirth).
