Solution
The correct option is C
Dura mater
Dura mater is the outermost layer of the meninges, which is made up of tough connective tissues to protect the internal structures. Further deep, we have the middle arachnoid membrane that is thin and cushions the brain and spinal cord. Pia mater is the most tender layer that allows water molecules and solutes to nourish the internal structure.
