Quizplus · Accepted Answer

Cutting the optic chiasm longitudinally will result in the fibers from the nasal halves of each retina crossing over to the opposite side, while the fibers from the temporal halves remain on the same side. This means that the medial half of each retina will be affected, resulting in blindness in the corresponding half of the visual field of each eye. Thus, the right half of the visual field of the right eye and the left half of the visual field of the left eye will be affected, resulting in blindness in both halves of the visual field. Therefore, D (all of the above) is the best choice.
