b) Is the neural connection between the hypothalamus and the neurohypophysis (posterior pituitary): The hypothalamic-hypophyseal tract consists of axons that transport oxytocin and ADH from the hypothalamus to the posterior pituitary for storage and release.

c) Conducts aldosterone to the hypophysis: Aldosterone is produced by the adrenal cortex and is not transported by this tract.

d) Is the site of prolactin synthesis: Prolactin is synthesized in the anterior pituitary, not in the hypothalamic-hypophyseal tract.
