Solution

The correct option is D Prolactin
Prolactin hormone is secreted by pituitary gland it stimulates the secretion of milk from mammals. It rises only when a baby suckles. Hormone oxytocin cause tiny muscles around the alveoli to squeeze the milk by using small tubes called milk ducts. Oxytocin is also responsible for contraction of uterus muscles, during and after birth. Prolactiiin and Oxytocin help the mother to form an emotional bond with her baby. Progesterone regulates the growth in size of alveoli and lobes. Estrogen stimulates the milk duct system to grow. Follicle stimulating hormone, luteinizing hormone and human chorionic gonadotropin control the level of estrogen and progesterone production.
