• A. Cornea
• B. Retina
• C. Optic nerve
• D. Lens

Answer: (B)

The retina is located at the back of the eye and contains light-sensing cells that convert incoming light into neural signals. Those signals travel via nerve fibers within the retina, which bundle together to form the optic nerve, carrying information to the brain for image interpretation. While focusing light onto the retina is done by the cornea and lens earlier in the path, the retina’s job is detection and initial processing of the light, not the focusing itself. The optic nerve then serves as the conduit that sends the processed signals to the brain.
