The correct option is C Prolactin - Milk ejection
Growth hormone (GH), FSH and prolactin are the hormones produced by the posterior pituitary gland. GH promotes the growth of the body, FSH stimulates the development of ovarian follicles and prolactin stimulates the synthesis of milk in breast.
Oxytocin secreted by the posterior pituitary stimulates uterine contraction during childbirth for foetal ejection.
