B. Wall of liver
C. Pubic symphysis
D. In between two vertebrae

Answer

### Step-by-Step Solution:

1. **Understanding the Term "Intervertebral Disc":**
- The term "intervertebral disc" refers to the structures located between the vertebrae in the vertebral column (spine).

2. **Identifying the Location:**
- Intervertebral discs are specifically found between adjacent vertebrae, which are the individual bones that make up the spinal column.

3. **Function of Intervertebral Discs:**
- These discs serve several important functions:
- They allow for limited movement between the vertebrae, making the joints slightly movable.
- They act as shock absorbers, cushioning the impact during activities such as walking or jumping.
- They protect the spinal nerves that exit the spinal cord.

4. **Eliminating Incorrect Options:**
- The question provides multiple choices, and we need to identify which one is correct:
- Intervertebral discs do not occur in the walls of the heart, the wall of the liver, or in the pubic symphysis.
- Therefore, the only correct answer is that intervertebral discs occur between the vertebrae.

5. **Final Answer:**
- The intervertebral disc occurs in the vertebral column, specifically between the vertebrae.
