The correct option is C Atrial natriuretic factor
Atrial natriuretic factor is a hormone secreted by the atrial wall of the heart. When there is an increase in the blood pressure, the atrial wall of the heart secretes atrial natriuretic factor (ANF). ANF causes the dilation of the blood vessels, which results in a decrease in blood pressure.
Epinephrine is a catecholamine, which is released by the adrenal medulla to cope with emergency situations. One of its effects is an increase in blood pressure.
Aldosterone is a mineralocorticoid released by the adrenal cortex. It is a vasoconstrictor, i.e., a hormone that narrows the diameter of blood vessels and increases the blood pressure.
Cortisol is a glucocorticoid released by the adrenal cortex. It is a stress hormone. It causes an increase in the heart rate and blood pressure.
