Answer 1

The correct option is A

aldosterone

Aldosterone is a hormone secreted by the adrenal cortex of the adrenal glands. It regulates the salt-water balance by acting on the kidneys. It also helps in maintaining blood pressure. Cortisol is also a secretion from cortex which assists in the synthesis of glucose from protein and fat. Norepinephrine and epinephrine are secretions from the medulla of adrenal glands.
