Detailed explanation-1: -Simple columnar The apical surfaces of these cells face the lumen and the opposite surface faces the basement membrane. The ovoid nuclei are usually placed towards basal surface. This type of epithelium is commonly adapted for secretion, absorption and protection.
Detailed explanation-2: -The correct answer: The type of epithelium that is most suitable for high levels of diffusion and filtration is E) Simple squamous. The simple squamous epithelium is the specific layer formed with the help of a flattened cell which forms an epithelial tissue structure.
Detailed explanation-3: -Simple squamous epithelial cells function as mediators of filtration and diffusion. Due to their simple and thin construct, they allow for easy transmembrane movement (i.e. across the membrane, and through the cell) of small molecules.
