Options
- AA-II, B-III, C-IV, D-V
- BA-I, B-IV, C-III, D-V
- CA-I, B-III, C-IV, D-II

Correct answer
D. A-I, B-III, C-IV, D-V
Step-by-step solution
The proximal convoluted tubule (PCT) is lined by simple cuboidal brush border epithelium which increases the surface area for reabsorption (A matches I). The descending limb of loop of Henle is permeable to water but almost impermeable to electrolytes, which concentrates the filtrate as it moves down (B matches III). The ascending limb is impermeable to water but allows transport of electrolytes actively or passively (C matches IV). The distal convoluted tubule (DCT) is capable of conditional reabsorption of Na ^+
