$(a)$ and $(c)$ are correct

Vedclass · Answer

(D) The secretion of aldosterone,a mineralocorticoid,is primarily regulated by the Renin-Angiotensin-Aldosterone System $(RAAS)$ and plasma electrolyte levels.$1$. Angiotensin-$II$: When blood pressure or blood volume decreases,the kidneys release renin,which leads to the production of angiotensin-$II$. Angiotensin-$II$ directly stimulates the adrenal cortex to secrete aldosterone.$2$. Plasma $K^+$ concentration: An increase in plasma potassium levels $(hyperkalemia)$ directly stimulates the adrenal cortex to release aldosterone to promote potassium excretion in the kidneys.Therefore,both plasma $K^+$ concentration and the level of blood angiotensin-$II$ are key regulators of aldosterone secretion.

The secretion of aldosterone by the adrenal cortex is directly controlled by:
