Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the meninges, which are protective layers surrounding the brain and spinal cord. These layers provide structural support and protection for the central nervous system.
2. Step 2: Learn the three meninges in order from outermost to innermost: dura mater (the tough, outermost layer), arachnoid mater (the middle, web-like layer), and pia mater (the delicate, innermost layer that adheres closely to the brain and spinal cord).
3. Step 3: Compare the options provided in the question to the correct order of the meninges. The correct sequence is dura mater, arachnoid mater, and pia mater.
4. Step 4: Eliminate the incorrect options by checking if they match the correct order. For example, 'Pia mater, arachnoid mater, dura mater' is incorrect because it lists the layers in reverse order.
5. Step 5: Confirm that the correct answer is 'Dura mater, arachnoid mater, pia mater,' as this matches the anatomical arrangement of the meninges from outermost to innermost.
