  • C

  • Correct answer
    D
    If both assertion and reason are false.

Solution

Pituitary gland or hypophysis is situated in a depression, the sella turcica of sphenoid bone of the skull. It is directly attached to the hypothalamus by a stalk, the infundibulum. Hypophysial portal veins carry blood containing neurohormones (releasing factors) from the hypothalamus to the anterior pituitary.

Hence, the correct answer is option: 'D'.
