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 but (R) is True.
2. Both (A) and (R) are True and (R) is the correct explanation of (A).
