Solution

The correct option is A Innermost meninges
Pia mater is the delicate innermost layer of the meninges.It is a thin fibrous tissue that is impermeable to the fluid that surrounds the cerebrospinal fluid and provides protection to the other layers of the meninges. It acts like a cushion of the brain. It allows blood vessels to pass through and nourish the brain. Hence option A is correct.
