B. Stilt
C. Moniliform
D. Fasciculated tuberous.

Answer

**Step-by-Step Solution:**

1. **Identify the Plant**: The question refers to the Dahlia plant, which is a genus of flowering plants.

2. **Understand Root Characteristics**: The roots of Dahlia are described as thick and fleshy. This characteristic is important because it indicates that the roots are specialized for storage.

3. **Analyze the Options**:
- **Option A: Fibrous Roots**: Fibrous roots are typically thin and not fleshy, and they are not primarily for storage. Therefore, this option is incorrect.
- **Option B: Stilt Roots**: Stilt roots are a type of adventitious root that provide support to the plant. Since Dahlia does not require this type of support, this option is also incorrect.
- **Option C: Monoliform Roots**: Similar to stilt roots, monoliform roots are also a type of adventitious root and are not suited for storage. Hence, this option is incorrect as well.
- **Option D: Fasciculated Tubers**: Fasciculated roots are thick and fleshy, designed for storage, which aligns with the characteristics of Dahlia roots.

4. **Conclusion**: Based on the analysis, the correct answer is that Dahlia has fasciculated tuberous roots, which are thick and fleshy, meant for storage.

**Final Answer**: In Dahlia, the roots are fasciculated tuberous roots.
