Vasopressin is released from the posterior pituitary gland in response to activation of hypothalamic osmoreceptors. It promotes water reabsorption in the kidneys, leading to decreased urine volume and increased concentration. It also causes vasoconstriction, leading to increased blood pressure. Therefore, it has characteristics of both A and C.
