A
PCT and thin descending loop of Henle
B
Thick ascending LOH and PCT
C
DCT and LOH
D
Collecting ducts and glomerular capsule
Explanation: 

Detailed explanation-1: -The descending limb of Henle’s loop is permeable to water but impermeable to electrolytes. This makes the filtrate concentrated as it moves down the Henle’s loop. The ascending limb is impermeable to water but permeable to electrolytes. Hence, the filtrate gets diluted as it passes the ascending loop region.
