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 & 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.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Ascending limb of 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 the light of the above statements, choose the correct answer from the options given below :

Given below are two statements: Statement I: In the nephron, the descending limb of loop of Henle is impermeable to water and permeable to electrolytes. Statement II: The proximal convoluted tubule is lined by simple columnar brush border epithelium and increases the surface area for reabsorption.
