Which option lists the protective cranial layers from outermost to innermost as described in the material?

The main idea is how the brain is protected by successive coverings and where the cushioning fluid sits. The outermost protective layer is the skull, a hard bone that shields the brain. Beneath that lies the dura mater, a tough, fibrous membrane that provides strong protection. Under the dura is the arachnoid mater, a thinner membrane. Between the arachnoid mater and the innermost layer, the pia mater, is a space called the subarachnoid space, which contains cerebrospinal fluid to cushion the brain. The pia mater itself closely adheres to the brain’s surface. So the order from outer to inner is the skull, dura mater, arachnoid mater, subarachnoid space (with CSF), and then pia mater.
