Which statement best describes the choroid?

• A. It is a transparent outer coat of the eye.
• B. It is the innermost layer of the retina.
• C. It is the vascular layer of the eye containing connective tissue.
• D. It is the white, fibrous outer layer.

Answer: (C)

The choroid is the vascular layer of the eye that lies between the sclera (the white outer coat) and the retina, and it contains connective tissue. This layer is rich in blood vessels, supplying oxygen and nutrients to the outer retina, including the photoreceptors, and it also contains pigment to absorb stray light and reduce glare. That description—being the vascular layer that contains connective tissue—best matches what the choroid actually is. The other statements point to other parts of the eye: the transparent outer coat is the cornea, the innermost retinal layer refers to components of the retina itself, and the white fibrous outer layer is the sclera.
