[2025-09-29T22:15:47.975767] [PI reasoning] **Identifying oral mucosa**

I need to clarify that oral mucosa refers to stratified squamous epithelium. In lining mucosa, it’s nonkeratinized and keratinized in masticatory mucosa. So, the best choice is option B: stratified squamous. I'm considering adding a citation to support this. It would be helpful to reference an anatomy or histology review article, possibly by recalling a PMID for accuracy. I should do a quick check to ensure I have the right source.
