Given below are two statements: one is labelled as Assertion \(A\) and the other is labelled as Reason \(R\). Assertion \(A\): Nephrons are of two types: Cortical and 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 \(A\) is false but \(R\) is true.
2. B Both \(A\) and \(R\) are true and \(R\) is the correct explanation of \(A\).
3. C Both \(A\) and \(R\) are true but \(R\) is NOT the correct explanation of \(A\).
4. D \(A\) is true but \(R\) is false.
