C
Explanation:
The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.
A) The Dura mater
B) The arachnoid mater
C) The pia mater
The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.
The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.
The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.

The results of Harlow's experiment were
overwhelming with an average infant monkey spending
17-18 hours per day on the
cloth mother and
less than an hour per day on the wire mother.
Harlow Harlow established the
nature of affection by experimenting on infant monkeys responses to compare the
influence of nursing from the influence of contact comfort. To study this, he compared
a wire mother who provided food, and a cloth mother who did not provide food.
The infant monkeys preferred contact comfort and spent more time with the cloth
mother than the wire mother.
