Solution
The correct option is A Aldosterone
The zona glomerulosa which is a part of the adrenal gland is principally responsible for the secretion of aldosterone, under the regulation of the renin-angiotensin system. Aldosterone causes an increase in salt and water reabsorption into the bloodstream from the kidney thereby increasing the blood volume, restoring salt levels and blood pressure.
