Assertion (A): Nephrons are of two types: Cortical & Juxta medullary, based on their relative position in the cortex and medulla.
Reason (R): Juxta medullary nephrons have a short loop of Henle whereas, cortical nephrons have a longer loop of Henle.
In the light of the above statements, choose the correct answer from the options given below:
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is NOT the correct explanation of A.
A is true but R is false.
A is false but R is true.
Assertion A is true, stating that nephrons are of two types: cortical and juxtamedullary, based on their relative position in the cortex and medulla.
However, Reason R is false. Juxtamedullary nephrons have a longer loop of Henle that extends deep into the medulla, while cortical nephrons have a shorter loop of Henle that does not extend as far into the medulla. The statement in Reason R is the opposite of the actual arrangement of the loop of Henle in cortical and juxtamedullary nephrons.
Therefore, while Assertion A is true, Reason R is false. The correct answer is Option 3 which is A is true but R is false.
