Final answer:

The correct order of the meninges from the neural tissue to bone is A. Pia mater, Arachnoid mater, Dura mater; with pia mater being the innermost layer, arachnoid mater the middle one, and dura mater the outermost layer.

Step-by-step explanation:

The correct order of the meninges from the neural tissue outwards towards the bone is pia mater, arachnoid mater, dura mater.

Therefore, the right answer is A. Pia mater, Arachnoid mater, Dura mater. The pia mater is the innermost layer that is in direct contact with the brain and spinal cord, the arachnoid mater is the middle web-like layer that contains the cerebrospinal fluid (CSF) in the subarachnoid space, and the dura mater is the thick, protective outermost layer anchored to the inner surface of the cranium.

These layers are essential for protecting the central nervous system and providing a supportive structure for the enclosed brain and spinal cord.
