The correct pairing sequence is:

The volume of the filtrate per day is $X$ liters and the volume of urine released per day is $Y$ liters. It means about $Z$ $\%$ of the filtrate is reabsorbed by the process of reabsorption.

The given figure shows the human excretory system with parts labeled $A$ to $D$. Select the option that correctly identifies these parts and describes their characteristics or functions.
