Which term describes the protective brain membranes as a group?

Explanation:
The protective brain membranes as a group are called the meninges. They consist of three layers: the dura mater (outer), the arachnoid mater (middle), and the pia mater (inner). Using the term meninges correctly describes all these coverings together, not just one or two of them. The other options refer to specific parts or spaces: the dura and pia are two of the layers, the choroid plexus makes cerebrospinal fluid within the ventricles, and the subarachnoid space is the gap between arachnoid and pia that contains CSF and vessels. So, meninges is the term that describes the protective brain membranes as a group.
