D) the eye

Quizplus · Accepted Answer

B is located at the optic chiasm, where the optic nerves from each eye cross over. This is the point where information from the left visual field is processed in the right hemisphere of the brain, and vice versa. The cerebral cortex (A) is the outer layer of the brain where visual processing occurs, but it is not located at B. The optic nerve (C) is the nerve that carries visual information from the eye to the brain, and it travels through B at the optic chiasm. The eye (D) is located before B, and it is where light enters and is focused to form an image.
