d none of these choices is correct
e epidural space

Explanation:

Cerebrospinal fluid (CSF) is a clear, colorless body fluid found in the brain and spinal cord. It fills the subarachnoid space, which is the space between the arachnoid mater and the pia mater. The subdural space is between the dura mater and the arachnoid mater and normally contains only a thin layer of fluid. Dural sinuses contain venous blood. The epidural space is outside the dura mater (in the spinal cord, it contains fat and blood vessels).

Answer:

B. subarachnoid space
