Solution

The correct option is A Pia, arachnoid and dura
The cord is sheathed in the same three meninges as it is the brain: the pia, arachnoid, and dura. The dura is the tough outer sheath, the arachnoid lies beneath it and the pia closely adheres to the surface of the cord.
The spinal cord is attached to the dura by a series of lateral denticulate ligaments emanating from the pial folds.

Therefore, the correct answer is option A.
