Solution
The correct option is B Oxytocin Oxytocin is released into the bloodstream at the time of parturition. It helps to develop strong contractions that eventually pushes out the baby from the womb. Oxytocin also stimulates the mammary glands to start producing milk. This process of milk secretion is called lactation.
