Solution
The correct option is C Destruction of dead blood corpuscles
The kidney is the excretory organ that helps to eliminate the waste product from the body.
It also helps to maintain the level of salts and water inside the body by the process of osmoregulation in the higher organism.
This is carried by vacuoles in some lower organisms. It also regulates the blood volume by regulating the amount of water excreted through the collecting duct by secretion of ADH hormone.
Destruction of dead red blood corpuscles is mainly carried in the spleen.
