Explanation / Answer

The paraventricular and supra optic nuclei present in the hypothalamus which is related to stress and physiological changes of body. The paraventricular nuclei releases oxytocin and the supra ventricular nuclei releases vasopressin in the general circulation. oxytocin is responsible for social bonding, childbirth, emotions ect and vasopressin or anti diuetic hormone is responsible for increase blood pressure by reabsorbing the fluids in kidney and contricts the blood vessels. So the answer is C
