Answer :
Final answer:
The Corpus Callosum is the nerve that links the two hemispheres of the brain, allowing them to share information and communicate with each other. The other nerves listed do not serve this function.
Explanation:
Based on the options provided, the nerve that links the two hemispheres of the brain is the Corpus Callosum (Option C). The Corpus Callosum, a thick bundle of neural fibers with about 200 million axons, acts as the primary communication bridge between the left and right hemispheres of the brain, enabling the two sides to exchange information. Therefore, if the Corpus Callosum is severed, the left and right hemispheres can no longer communicate effectively. Other nerves like the optic nerve, the spinal nerve, and the facial nerve do not connect the two hemispheres of the brain.
