Solution

The correct option is B Oxytocin/Pitocin
Sometimes the labor pains is less and uterine contractions have to be induced then doctors inject to facilitate delivery oxytocin. In women, oxytocin is crucial as it is involved in the birth process – by causing uterine contractions during labour as well as shrinking the uterus after delivery. Furthermore, during breastfeeding, oxytocin is released, which promotes the production of milk. Therefore, oxytocin stimulates the contraction of smooth muscles in the uterus at the time of childbirth and the ejection of milk from mammary glands.
