Which membrane lies directly posterior to the corneal stroma?

Explanation:
Descemet's membrane lies directly posterior to the corneal stroma. It is the basement membrane of the corneal endothelium, forming the boundary between the stroma and the endothelium. Bowman's membrane is anterior to the stroma, just beneath the epithelium, while the endothelium sits behind Descemet's membrane. Understanding this arrangement shows why Descemet's membrane is the correct choice.
