The answer is the third one (or C): Pia Mater.

Explanation for each option:

  1. Dura Mater: This is the outermost layer of the meninges and is not adhered to the surface of the brain. It forms the tough outer covering and contains sinuses that carry venous blood.
  2. Arachnoid Mater: This is the middle layer of the meninges and is not directly adhered to the surface of the brain. It has a web-like structure and contains cerebrospinal fluid.
  3. Pia Mater: This is the innermost layer of the meninges and is directly adhered to the surface of the brain, following its contours closely.

Summary: The Pia Mater is the layer of the meninges that is adhered to the surface of the brain.
