B. Raphanus sativus and Daucus carota
C. Colocasia and Allium
D. Chrysanthemum and Tecoma

Answer

To determine which of the options provided is a fleshy root, we need to first understand what a fleshy root is. Fleshy roots are modified roots that serve as storage organs for nutrients and energy. They are typically thick and swollen, allowing them to store food.

### Step-by-Step Solution:

1. **Understanding Fleshy Roots**:
- Fleshy roots are modified roots that store food and nutrients. Common examples include carrots and beetroots, which are both tuberous roots.

2. **Analyzing the Options**:
- **Option A: Ficus bagelinensis and Solanum tuberosum**:
- Ficus bagelinensis is the banyan tree, which is a woody plant and does not have fleshy roots. Solanum tuberosum, on the other hand, refers to the potato, which is a tuber but not a root.
- **Option B: Raphanus sativus and Daucus carota**:
- Raphanus sativus is the radish, and Daucus carota is the carrot. Both of these are examples of fleshy roots, as they are modified taproots that store food.
- **Option C: Colocasia and Allium**:
- Colocasia (taro) is a flowering plant and not a fleshy root. Allium (like onions) is also not a fleshy root.
- **Option D: Chrysanthemum and Tecoma**:
- Chrysanthemum is a flowering plant, and Tecoma is a shrub; neither of these are fleshy roots.

3. **Conclusion**:
- After analyzing all the options, the correct answer is **Option B: Raphanus sativus and Daucus carota**, as both are examples of fleshy roots.

### Final Answer:
The fleshy root is **Option B: Raphanus sativus and Daucus carota**.
