Answer:
Correct Answer: D
Solution:
Simple epithelium doesn?t cover surfaces exposed to mechanical or chemical abrasions, because it is made up of a single layer of cells, hence it is not effective in protecting the underlying tissue.
Simple epithelium occurs mainly on secretory and absorptive surfaces.
There is another types of epithelial tissue called compound epithelium which being multilayered is effective in providing protection to underlying tissues, hence covers the surfaces exposed to mechanical and chemical abrasions.
