(c)
The posterior pituitary gland secretes two hormones, vasopressin (or ADH) and oxytocin. Vasopressin regulates the body’s water balance. Oxytocin plays a role in lactation by stimulating the ejection of milk from the breast in response to sucking but milk production is promoted by prolactin secreted by the anterior pituitary.
