Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R): 
Assertion (A): The filtrate gets concentrated as it moves down the descending limb of loop of Henle in the human nephron.
Reason (R): The descending limb of loop of Henle is impermeable to water but allows transport of electrolytes actively or passively.
In the light of the above statements choose the correct answer from the options given below:
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
