Explanation:

Identify the highlighted structure

Using the Eye Anatomy and Neural Components knowledge points

• The provided cross-sectional diagram of the eye highlights a thin, inner layer lining the posterior portion of the globe in bright green.
• This innermost, light-sensitive neural layer of the eye is the retina.
• The other options represent different structures: the optic disc is the exit point of the optic nerve, the ora serrata is the serrated junction between the retina and the ciliary body, the lens is the biconvex structure behind the pupil, and the optic nerve (CN II) exits posteriorly. Therefore, the highlighted green layer is the retina.
