The question is referring to split brain surgery, which involves severing the corpus callosum. Option A is incorrect because cranial surgery may refer to any surgery performed on the cranium, and temporal lobe surgery is not typically used for epilepsy. Option C is incorrect because split brain surgery involves the corpus callosum, not a cranial nerve. Option D is incorrect because the thalamus is not severed in split-brain surgery.
