Solution
The correct option is A Brain and Spinal cord Three layers of protective tissue that surround the brain and spinal cord are called meninges. These three layers are dura mater, arachnoid mater, and pia mater.
-Dura mater is the outermost layer that separates the cranial cavity into compartments and protects the brain.
-Arachnoid mater is the middle layer of the meninges.
-Pia mater is the innermost layer of the meninges and adheres to the brain.
