Removal of the proximal convoluted tubule from the nephron will result in:

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:

Which of the following is mismatched?

$I.$ Reabsorption of water occurs passively in the initial segment of nephron.
$II.$ Nitrogenous wastes are absorbed by active transport.
$III.$ Conditional reabsorption of $Na^{+}$ and water takes place in $DCT$.
$IV.$ $DCT$ reabsorbs glucose.
$V.$ $DCT$ is capable of selective secretion of $H^{+}$,$K^{+}$ and $NH_{3}$ to maintain $pH$ and $Na^{+}-K^{+}$ balance in blood.
$VI.$ Substances like glucose,amino acids,$Na^{+}$,etc.,in the filtrate are reabsorbed actively.
Choose the option with incorrect statements.

Match the following parts of a nephron with their function:

$(a)$ Descending limb of Henle's loop	$(i)$ Reabsorption of salts only
$(b)$ Proximal Convoluted tubule	$(ii)$ Reabsorption of water only
$(c)$ Ascending limb of Henle's loop	$(iii)$ Conditional reabsorption of sodium ion and water
$(d)$ Distal convoluted tubule	$(iv)$ Reabsorption of ion,water and organic nutrients

Select the correct option from the following:

Cuboidal epithelium with brush border of microvilli is found in:
