Correct answer: "The body releases more and more hormones to cause more contractions to help push the baby out."
Explanation: Labor is a positive‑feedback loop. Stretch receptors in the cervix signal the posterior pituitary to release oxytocin, which intensifies uterine contractions. Stronger contractions increase cervical stretching, which triggers more oxytocin release, and the cycle continues until the baby is delivered (when the stimulus — cervical stretch — ends). The first option describes negative feedback (slowing a process), and the insulin option is unrelated to the labor positive‑feedback mechanism.
