Solution

The correct option is C Sodium ion
The ascending limb of loop of Henle is a segment of the nephron in the kidney divided into a thin and thick ascending limb. The thin ascending limb is impermeable to water and ions, except sodium and chloride, which cross by diffusion. In thick ascending limb, sodium (Na), potassium (K) and chloride (Cl) ions are reabsorbed by active transport.
