Step-by-step solution

The descending limb of loop of Henle is permeable to water but almost impermeable to electrolytes (A-II). The ascending limb is impermeable to water but allows transport of electrolytes actively or passively (B-I). The vasa recta is a U-shaped capillary network that runs parallel to the Henle's loop. The counter current exchange in vasa recta helps to maintain the concentration gradient in the medullary interstitium (C-III). The collecting duct is a long duct from which large amounts of water could be reabsorbed to
