The walls of kidney tubules are formed by epithilium, which functions in resorbing materials filtered from blood plasma such as nutrients, ions, and water.
a) stratified columnar
b) stratified squamous
c) simple cuboidal
d) stratified cuboidal
e) simple squamous

The correct option is : C) simple cuboidal epithilium

Explanation:

The simple cuboidal epithelium consists of only one layer of cuboidal cells that have a cube-like shape and also appear square-shaped in cross-section. The nucleus of the cuboidal epithelial cell is large and is present in the center of the cell.

The simple cuboidal epithelium is commonly found in the lining of the kidney tubules and are responsible for the reabsorption of the nutrients, ions and water from the tubular fluid.
