Solution

The correct option is D Parturition
At the end of the gestation period, the uterus contracts vigorously which causes expulsion/ delivery of the foetus. This process of delivery of the foetus (childbirth) is called as parturition. It takes place under the influence of a hormone oxytocin which is produced by anterior pituitary. Oxytocin acts on the uterine muscle and causes stronger uterine contractions.
So, the correct answer is option D.
