Which of the following would help in prevention of diuresis?

(A)Reabsorption of Na+ and water from renal tubules due to aldosterone
(B)Atrial natriuretic factor causes vasoconstriction
(C)Decrease in secretion of renin by JG cells
(D)More water reabsorption due to undersecretion of ADH

The NCERT line that answers it

Verbatim line

Aldosterone acts mainly at the renal tubules and stimulates the reabsorption of $\text{Na}^+$ and water and excretion of $\text{K}^+$ and phosphate ions.

Chapter: Chemical Coordination and Integration
Section: 19.2.7 Adrenal Gland

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states that aldosterone stimulates reabsorption of Na+ and water at renal tubules, which directly matches the mechanism described in option A for preventing diuresis.
