B. Gray mater of brain
C. Between duramater and arachnoid
D. Gray mater of spinal cord

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks about the innermost meninx, which refers to the protective layers surrounding the brain.

2. **Identifying the Meninges**: There are three layers of meninges:
- **Dura Mater**: The outermost layer, tough and protective.
- **Arachnoid Mater**: The middle layer, which is web-like.
- **Pia Mater**: The innermost layer, which is delicate and closely adheres to the surface of the brain.

3. **Locating the Pia Mater**: The Pia Mater is the innermost meninx and is found directly on the surface of the brain. It invests in the brain tissue and follows the contours of the brain.

4. **Association with Gray Matter**: The Pia Mater is specifically associated with the gray matter of the brain, which contains neuronal cell bodies.

5. **Conclusion**: Therefore, the innermost meninx (Pia Mater) is found invested in the gray matter of the brain.

6. **Final Answer**: The correct answer is that the innermost meninx is found in the gray matter of the brain.
