Read the following functions and identify the part of nephron responsible for it. A. Nearly all of the essential nutrient and 70-80% of electroytes and water are reabsorbed by this segement. B. Conditional reabsorption of Na^(+) and water takes place in this segement. C. Large amounts of water could be reabsorbed from this region to produce concentrated urine.

Which of theses statements about proximal convoluted tubule is/are true? I. it is lined by simple columnar brush border epithelium which increases the surface area for reabsorption. II Nearly all of the essential nutrients and 70%-80% of electrolytes and water are reabsorbed by this segment. III. It selectively secretes hydrogen ions, ammonia and potassium ions into the filtrate. IV. It is the most convoluted part of the nephron and is present in the medullary region of the kidney.

Assertion :- In PCT all of the essential nutrient and 70-80 percent of electrolytes and water are reabsorbed. Reason :- PCT is lined by simple cuboidal brush border epithelium which increases the surface , are for reabsorption.
