Choroid, ciliary body, and iris

Retina, optic nerve, and sclera

Verified step by step guidance1
Understand that the eye is composed of three main layers: the fibrous layer, the vascular layer, and the inner layer.
Identify the components of the vascular layer, which is also known as the uvea.
Recall that the vascular layer of the eye includes structures that are rich in blood vessels and are responsible for providing nutrients and oxygen to the eye.
Recognize that the choroid, ciliary body, and iris are part of the vascular layer, as they are involved in blood supply and regulation of light entering the eye.
Eliminate the other options by identifying that the retina and optic nerve are part of the inner layer, while the sclera is part of the fibrous layer, and the conjunctiva, vitreous humor, and macula are not part of the vascular layer.
