The cranial meninges are the three layers of protective membranes that surround the brain and spinal cord. The three layers of the cranial meninges are the dura mater, arachnoid, and pia mater. The dura mater is the outermost layer, followed by the arachnoid and then the innermost layer, pia mater. The corpus callosum is not a part of the cranial meninges. It is a bundle of nerve fibers that connects the two hemispheres of the brain and allows for communication between them. Therefore, option D is the correct answer.
