Question

The secretion of aldosterone by adrenal cortex is directly controlled by

• A. Plasma $K^{+}$ concentration
• B. Plasma Ca concentration
• C. Level of blood angiotensin
• D. Both A and C

Aldosterone secretion by the zona glomerulosa of the adrenal cortex is controlled by circulating factors including the renin angiotensin system(RAS) and potassium concentration.

So, option A is the correct option.
