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)
