The outer layer of the optic cup forms which tissue?

Explanation:
During early eye development, the optic cup forms from the invaginated optic vesicle and has two layers that take different fates. The outer layer differentiates into the retinal pigment epithelium, a pigmented cell layer that supports the photoreceptors and interfaces with the choroid. The inner layer becomes the neural retina, which processes visual information. The lens epithelium and corneal epithelium come from surface ectoderm, not from the optic cup, so they are not formed by the outer layer. Thus, the outer layer of the optic cup forms the retinal pigment epithelium.
