The visual signals travel from the eye to the brain via the optic nerve. The optic nerve fibers from each eye cross over at the optic chiasm, with half the fibers from each eye continuing onto the opposite side of the brain. From the optic chiasm, the visual signals travel to the thalamus, which acts as a relay station. Finally, the visual signals arrive at the occipital lobe, where the visual cortex is located, responsible for processing visual information. Thus, the correct pathway is optic nerve - optic chiasm - thalamus - occipital lobe, making option B the correct choice.
