D. Lumbar , thoracic, sacral, cervial.

Answer

To determine the correct order of vertebrae in the human vertebral column, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Vertebral Column**: The human vertebral column is made up of 26 vertebrae arranged in a specific order.

2. **Identify the Regions of the Vertebral Column**:
- **Cervical Vertebrae**: There are 7 cervical vertebrae located in the neck region.
- **Thoracic Vertebrae**: There are 12 thoracic vertebrae located in the upper back, attached to the ribs.
- **Lumbar Vertebrae**: There are 5 lumbar vertebrae located in the lower back.
- **Sacral Vertebrae**: There is 1 sacral vertebra, which is fused to form the sacrum.
- **Coccygeal Vertebrae**: There is 1 coccygeal vertebra, which is fused to form the coccyx (tailbone).

3. **Arrange the Regions in Order**: Starting from the top (near the skull) to the bottom, the order of the vertebrae is:
- Cervical (C)
- Thoracic (T)
- Lumbar (L)
- Sacral (S)

4. **Conclude the Correct Order**: Therefore, the correct order of the vertebrae in the human vertebral column is:
- **Cervical, Thoracic, Lumbar, Sacral**.

5. **Select the Correct Option**: Based on the options provided, the correct answer is option A: Cervical, Thoracic, Lumbar, Sacral.

### Final Answer:
The correct order of vertebrae is: **Cervical, Thoracic, Lumbar, Sacral** (Option A).
