Which is NOT one of the four well-defined mucosal compartments for bacteria location?

Explanation:
Bacteria localization on mucosal surfaces is described in distinct habitats: they can be in free mucus within the lumen, embedded in adherent mucus that coats the mucosa, attached to the surface epithelium, or residing within the epithelial cells themselves. The lamina propria lies beneath the epithelium as connective tissue containing immune cells and vasculature; it is not a mucosal compartment where luminal bacteria normally reside. Bacteria there would indicate epithelial breach and invasion, not a regular mucosal dwelling site. So, this option does not fit as one of the defined mucosal compartments for bacteria location.
