Which one of the following hormones though synthesised elsewhere, is stored and released by the master gland?

Neurohypophysis (pars nervosa) also known as posterior pituitary, stores and releases two hormones called oxytocin and vasopressin (Anti Diuretic Hormone- ADH), which are actually synthesised by the hypothalamus and are transported axonally to neurohypophysis.Prolactin, MSH and LH are secreted and released by the Adenohypophyses (Anterior pituitary gland) itself.
