Options

A. Cornea
B. Choroid
C. Sclera
D. Conjunctiva

Answer

B

Explanation

Choroid is the posterior portion of the vascular tunic and lines the internal surface of the sclera. It also contains melanocytes that produce the pigment melanin which absorbs stray light rays which prevent reflection and scattering of light within the eyeball. As a result, the image cast on the retina by the cornea and lens remains sharp and clear.
