Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R)
Assertion (A):  Ascending limb of the loop of Henle is impermeable to water and allows transport of electrolytes actively or passively. 
Reason (R):  Dilution of filtrate takes place due to efflux of electrolytes in the medullary fluid

In light of the above statements, choose the correct answer from the options given below:
1.  (A) is True, (R) is False
2.  (A) is False, (R) is True
3.  Both (A) and (R) are True and (R) is the correct explanation of (A)
4.  Both (A) and (R) are True but (R) is not the correct explanation of (A)

Given below are statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Nephrons are of two types: Cortical & Juxta medullary, based on their relative position in cortex and medulla.
Reason (R): Juxta medullary nephrons have short-loop of Henle whereas, cortical nephrons have longer loop of Henle.
In the light of the above statements, choose the correct answer from the options given below:
1. (A) is False, (R) is True.
2. Both (A) and (R) are True and (R) correctly explains (A).
