To solve the question "All given modifications belong to adventitious roots, except," we will analyze each option provided and determine whether it belongs to adventitious roots or not.

### Step-by-Step Solution:

1. **Understand Adventitious Roots**:
- Adventitious roots are roots that arise from non-root tissues, such as stems or leaves. They can develop from nodes or internodes of the plant.

2. **Analyze Each Option**:
- **Option A: Reproductive roots of Asparagus**:
- These roots develop in clusters at the base of the stem and are swollen for food storage. They are considered adventitious roots.

- **Option B: Storage roots of Sweet Potato**:
- These roots arise from the nodes of the running stem and are known as edible root tubers. They are also classified as adventitious roots.

- **Option C: Conical roots of Carrot**:
- These roots are modifications of the tap root, which grows vertically downward. Since they are derived from the main root system and not from non-root tissues, they do not belong to adventitious roots. This is the exception.

- **Option D: Prop roots of Banyan Tree**:
- These roots arise from the horizontal aerial branches of the tree and provide support. They are classified as adventitious roots.

3. **Conclusion**:
- The only option that does not belong to adventitious roots is **Option C: Conical roots of Carrot**. Therefore, this is the correct answer.

### Final Answer:
**Option C: Conical roots of Carrot** is the modification that does not belong to adventitious roots.
