The given question is not complete, the complete question is:

Which of the three spinal meninges is the most superficial?

A) Arachnoid mater

B) Dura mater

C) Meninx mater

D) Pia mater

E) Epi mater

The correct answer is option B, that is, dura mater.

Explanation:

The three of the membranes that envelopes the spinal cord are known as the spinal meninges. These are the arachnoid mater, dura mater, and the pia mater. These membranes comprise a cerebrospinal fluid, that helps in protecting and supporting the spinal cord.  

Of the three spinal meninges, the dura mater is the most superficial one. Of all the meninges, the most external one is the dura mater. It covers the space between the foramen magnum to the filum terminale and is distinguished from the boundaries of the vertebral canal via the epidural space.
