Solution

The correct option is D Descending limb of loop of Henle to the ascending limb of vasa recta
Transport of substances facilitated by the special arrangement of Henle’s loop and vasa recta is called the counter current mechanism. Water is reabsorbed from the descending limb of Henle’s loop and is exchanged with ascending limb of vasa recta.
