Which statement is true regarding the meninges of the brain?

Explanation:
The protective membranes surrounding the brain consist of three layers: the outermost dura mater, the middle arachnoid mater, and the innermost pia mater. The dura mater lines the inside of the skull, forming a tough protective outer layer. The pia mater directly covers the brain's surface, following its contours, while the arachnoid lies between them and contains cerebrospinal fluid in the subarachnoid space. Therefore, the true statement is that the dura coats the skull and the pia coats the brain. The other options mix up which layer covers which structure, or incorrectly say the meninges aren’t involved in protection.
