Which portion of the brain does the internal carotid artery predominantly supply?

Internal carotid arteries predominantly supply the anterior circulation of the brain, including the frontal and parietal lobes and portions of the temporal lobe, as well as ocular structures via the ophthalmic artery. This is why the correct choice emphasizes the anterior brain and eyes. The posterior circulation—feeding the brainstem, cerebellum, and occipital lobes—comes mainly from the vertebral-basilar system, not the internal carotid. So statements describing spinal cord/medulla or posterior brain regions don’t fit as well, and the description of anterior brain plus eyes best captures the main territory supplied by the internal carotid.
