Cutting the optic chiasm longitudinally will result in visual information being presented to only one hemisphere. If the cut is made to the right of the chiasm, the left hemisphere will receive the visual information. If the cut is made to the left of the chiasm, the right hemisphere will receive the visual information. Blindfolding one eye will not necessarily present visual information to only one hemisphere as each eye sends information to both hemispheres. Therefore, the best choice is E, which involves cutting the optic chiasm longitudinally and blindfolding the right eye to present information only to the left hemisphere.
