What is the correct sequence for parturition to occur?
A. Signal from fetus and placenta → Uterine contractions → Release of oxytocin → Rise in oxytocin secretion → Powerful contractions → Parturition
B. Uterine contractions → Release of oxytocin → Rise in oxytocin secretion → Powerful contractions → Signal from fetus and placenta → Parturition
C. Signal from fetus and placenta → Release of oxytocin → Uterine contractions → Rise in oxytocin secretion → Powerful contractions → Parturition
D. Release of oxytocin → Uterine contractions → Signal from fetus and placenta → Rise in oxytocin secretion → Powerful contractions → Parturition
