Final answer:

The correct visual tract from the binocular visual field involves the contralateral nasal retina and ipsilateral temporal retina projecting to the contralateral occipital lobe, ensuring the left visual field is processed in the right occipital lobe and the right visual field in the left. The correct option is B. Projects to the ipsilateral nasal retina and ipsilateral temporal retina; terminates in the ipsilateral occipital lobe

Step-by-step explanation:

The correct tract from the binocular visual field is Projects to the contralateral nasal retina and ipsilateral temporal retina; terminates the contralateral occipital lobe. This means that the visual information from the right side visual field projects to the nasal retina of the left eye and the temporal retina of the right eye, and vice versa for the left side visual field. The optic tract fibers from the nasal retinas cross at the optic chiasm and project to the opposite side of the brain, while the temporal retina fibers stay on the same side. Consequently, the left visual field is processed in the right occipital lobe and the right visual field is processed in the left occipital lobe, maintaining the topographic relationship throughout the visual pathway.

The correct option is B. Projects to the ipsilateral nasal retina and ipsilateral temporal retina; terminates in the ipsilateral occipital lobe
