Hormone responsible for the absorption of water in $DCT$ is

The amount of the original filtrate volume which is reabsorbed by the time the tubular fluid enters the Henle's loop is approximately (in $\%$)

Match the following columns:

Column-$I$	Column-$II$
$a. PCT$	$i. \text{Selective secretion of } H^+ \text{ and } K^+ \text{ ions}$
$b. DCT$	$ii. 70-80\% \text{ of electrolytes and water reabsorption}$
$c. \text{Descending limb}$	$iii. \text{Allows passage of small amounts of urea}$
$d. \text{Ascending limb}$	$iv. \text{Permeable to water}$
$e. \text{Collecting duct}$	$v. \text{Permeable to salts}$

Statement $I$: Collecting duct of kidney extends from the cortex to the inner parts of medulla.
Statement $II$: Large amount of water could be reabsorbed from collecting duct to form a concentrated urine.

Which of the following is mismatched?

Where does the selective reabsorption of glomerular filtrate take place?
