I believe it is stratified squamus epithelium.
Hope this helps!
Answer:
The type of epithelium that lines the inferior portions of the pharynx is stratified squamous epithelium.
Explanation:
The pharynx is a structure made up of muscles and mucous membranes -like many internal organs- that is part of the respiratory system and is an intermediate step in the digestive tract.
This structure has two portions:
- <em>Upper or nasopharynx
</em>
- <em>Lower, or oropharynx, in contact with the airways.
</em>
Some even propose that the borderline surface between the pharynx and larynx can be called the laryngopharynx, due to its tissue structure.
The lower portion of the pharynx is covered by a squamous stratified epithelium, the inner layers of which rest on a basal lamina. The more superficial layers provide protection to the interior of the pharynx against friction, in addition to remaining lubricated by mucous secretion at that level.

The correct answer is that it becomes cancer cells.
Mitosis refers to the kind of cell differentiation, which leads to the formation of two daughter cells, and each comprising the same type and amount of chromosomes as the parent nucleus, generally of ordinary tissue growth.
The process of mitosis should be error free as otherwise healthy cells can turn into cancer cells. Cancer is basically a disorder of mitosis, in this case, the usual checkpoints, which are monitoring mitosis are overridden or ignored by the cancer cells.
Cancer initiates when a single cell is converted or transformed into a normal cell to a cancer cell and is generally taking place due to a modification in function of one of many genes, which usually work to monitor growth, like p53 gene or tumor suppressor gene.
