पर्याय

• i and ii only

• ii and iii only

• ii and iv only

i only

Explanation:

Antidiuretic Hormone (ADH) increases water reabsorption in the kidneys without significantly increasing salt reabsorption. This addition of “pure” water to the bloodstream dilutes the blood, thereby decreasing its overall osmolarity.
