Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The cranial meninges consist of an outer arachnoid, a middle dura mater, and an inner pia mater. Reason (R): The human brain is well protected by cranial meninges. In the light of the above statements, choose the most appropriate answer from the options given below:

Step-by-step solution

Assertion (A) is incorrect because the correct sequence of the cranial meninges from the outside to the inside is: outer dura mater, middle arachnoid, and inner pia mater. Reason (R) is correct as the human brain is indeed well protected by the cranial meninges located inside the skull. Therefore, the Assertion is incorrect but the Reason is correct. Answer: Assertion is incorrect but Reason is correct.
