Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the presence of intervertebral discs in the vertebral column of certain animal groups: birds, reptiles, mammals, and amphibians.

2. **Identifying the Correct Group**: Intervertebral discs are specialized structures found in the vertebral column. They are primarily associated with mammals.

3. **Location of Intervertebral Discs**: These discs are located between the bodies of adjacent vertebrae, starting from the second cervical vertebra down to the sacrum in mammals.

4. **Structure of Intervertebral Discs**: Each intervertebral disc consists of two main components:
- An outer fibrous ring made of fibrocartilage.
- A soft, pulpy, and highly elastic inner substance.

5. **Function of Intervertebral Discs**: The intervertebral discs serve several important functions:
- They form strong joints that allow for various movements of the vertebral column.
- They absorb vertical shocks during activities such as walking or jumping.

6. **Conclusion**: Based on the above information, the correct answer to the question is that intervertebral discs are found in the vertebral column of mammals.

**Final Answer**: Intervertebral discs are found in the vertebral column of mammals.
