Given below are two statements:
Statement $I$: In the nephron,the descending limb of the 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.
In the light of the above statements,choose the correct answer from the options given below:

Classify the following substances as actively or passively transported during the reabsorption of $GFR$: glucose,amino acids,nitrogenous wastes,$Na^+$,water.
