Answer: (E)

Verified step by step guidance

1. Begin by identifying the function of the corpus callosum. It is a large bundle of nerve fibers that connects the two hemispheres of the brain.
2. Understand the role of the corpus callosum in facilitating communication between the right and left cerebral hemispheres, allowing for the integration of motor, sensory, and cognitive performances between the two sides.
3. Review the anatomy of the brain to locate the cerebral hemispheres. These are the two halves of the brain, known as the left and right hemispheres, which are responsible for different functions and processes.
4. Consider the options provided in the problem. The cerebellum and spinal cord, pituitary and hypothalamus, gray and white matter of the spinal cord, and pons and medulla are not connected by the corpus callosum.
5. Conclude that the corpus callosum specifically connects the right and left cerebral hemispheres, facilitating communication and coordination between them.
