C. Mango
D. All of these

Explanation

To determine the monocarpic plant from the options given (bamboo, litchi, mango, or all of these), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Monocarpic Plants**:
- Monocarpic plants are those that flower and produce seeds only once in their lifetime.

2. **Evaluate Each Option**:
- **Bamboo**:
- Bamboo is known to be monocarpic. For example, the species *Bambusa tulda* flowers once every 5200 years, after which it produces a large number of seeds and then dies.
- **Litchi**:
- Litchi is not monocarpic; it is polycarpic. A litchi tree can flower multiple times throughout its life, producing fruit each time.
- **Mango**:
- Similar to litchi, mango trees are also polycarpic. They flower and produce fruit annually.
- **All of These**:
- Since both litchi and mango are polycarpic, this option is incorrect.

3. **Conclusion**:
- The only monocarpic plant from the options provided is **bamboo**.

### Final Answer:
The monocarpic plant out of the given options is **bamboo**.
