Compare the statements $A$ and $B$.
$\text{Statement } A$: When the urine moves through the descending limb,it becomes hypertonic,and as it passes through the ascending limb of Henle's loop,it becomes hypotonic.
$\text{Statement } B$: The descending limb is permeable to sodium ions,while the ascending limb is impermeable to sodium ions.

A
Statement $A$ is correct and $B$ is incorrect.
B
Statement $A$ is wrong and $B$ is correct.
C
Both statements $A$ and $B$ are incorrect.
D
Both statements $A$ and $B$ are correct.
Solution
(A) Statement $A$ is correct and $B$ is incorrect.
The descending limb of Henle's loop is permeable to water but nearly impermeable to electrolytes. As the filtrate moves down,water is reabsorbed,making the filtrate hypertonic.
The ascending limb of Henle's loop is impermeable to water but allows the transport of electrolytes (like $Na^+$) out of the tubule. This makes the filtrate hypotonic.
Statement $B$ is incorrect because the descending limb is actually impermeable to sodium ions,whereas the ascending limb is permeable to sodium ions (via active transport).
