The Human Brain is well protected by the skull. Inside the skull, the brain is covered by cranial meninges consisting of three coverings which are as follows :

1. Pia mater: The pia mater is the innermost layer of the meninges, and it is located closest to the surface of the brain and spinal cord.
2. Arachnoid: The arachnoid mater is the middle layer of the meninges, positioned between the pia mater and the dura mater.
3. Dura mater: The dura mater is the outermost and toughest layer of the meninges, providing protection for the brain and spinal cord.
Therefore, the correct answer is Option 3 which is - III; I; II.
