After crossing at the optic chiasm, which structure carries the crossed fibers?

Explanation:
Crossing at the optic chiasm swaps the nasal-retina fibers to the opposite side, and after this crossing they travel in the optic tract on the other side toward the brain. So the crossed fibers are carried by the optic tract (which then relays to the lateral geniculate body). The optic nerve is before the chiasm, and the lateral geniculate body and superior colliculus are downstream relay centres, not the carrier of the crossed fibers themselves.
