Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
ADH increases the permeability of H2O in the Proximal Convoluted Tubule.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -ADH is secreted by pituitary gland. It increases the water permeability of distal convoluted tubules and collecting tubules, hence, plays a significant role in water re-absorption. The absence of ADH will reduce water reabsorption which may lead to water diuresis or diabetes insipidus.

Detailed explanation-2: -So, the correct option is ‘Collecting tubule’.

Detailed explanation-3: -Water excretion by the kidney is regulated by the peptide hormone vasopressin. Vasopressin increases the water permeability of the renal collecting duct cells, allowing more water to be reabsorbed from collecting duct urine to blood.
