Options

A. Retina `to` Sclera ` to` Choroid
B. Retain ` to `Choroid ` to` Sclera
C. Sclera ` to` Choroid ` to` Retina
D. Sclera `to` Retina ` to` Choroid

Answer

To solve the question regarding the centripetal arrangement of the three wall layers of the eyeball, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Layers of the Eyeball**:
The human eyeball consists of three main layers:
- **Sclera**: The outermost layer.
- **Choroid**: The middle layer.
- **Retina**: The innermost layer.

2. **Understanding the Arrangement**:
- The **sclera** is the tough, white outer layer of the eye that provides structure and protection.
- The **choroid** is located beneath the sclera and contains blood vessels that supply nutrients to the eye.
- The **retina** is the innermost layer that contains photoreceptor cells (rods and cones) responsible for detecting light and sending signals to the brain.

3. **Correct Sequence**:
Based on the arrangement from the outermost to the innermost layer, the correct sequence is:
- **Sclera** (outer layer)
- **Choroid** (middle layer)
- **Retina** (inner layer)

4. **Conclusion**:
Therefore, the correct answer to the question about the centripetal arrangement of the three wall layers of the eyeball is:
- **Sclera, Choroid, Retina**.

### Final Answer:
**Sclera, Choroid, Retina** (Option 3).
