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 'Aldosterone acts mainly at the renal tubules and stimulates the reabsorption of Na⁺', which directly and conclusively establishes that increased aldosterone causes increased sodium reabsorption, matching the correct answer.
