Solution
The correct option is C Perfusion
Reabsorption is an important function of the kidney where water and solutes are removed from the tubule and return back to the blood.
Secretion is an opposite function of reabsorption where the waste is removed from blood capillaries and excreted out of the body.
Filtration is also a renal function as it passes the solute and water from the plasma to the renal tubule.
Here perfusion stands as an odd one as it is not a renal function. It is a process of passage of fluid through the circulatory system to an organ or a tissue.
