Answer

To answer the question regarding which plant has lateral branches that originate from the basal and underground portion of the main stem, grow horizontally beneath the soil, and then come out obliquely upward to give rise to leafy shoots, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question describes a specific type of stem modification where lateral branches grow underground and then emerge to form new shoots.

2. **Identifying the Type of Stem Modification**: This type of stem modification is related to vegetative propagation, where new plants arise from parts of the parent plant without the involvement of seeds.

3. **Analyzing the Characteristics**: The key characteristics mentioned include:
- Lateral branches originating from the basal and underground portion of the main stem.
- Horizontal growth beneath the soil.
- Emergence of leafy shoots from these branches.

4. **Considering Examples of Plants**:
- **Banana**: Known for having underground rhizomes.
- **Pineapple**: Has a unique growth pattern with lateral branches that fit the description.
- **Chrysanthemum**: Also known to propagate through underground structures.

5. **Selecting the Correct Answer**: Among the examples considered, **Pineapple** is the plant that specifically fits the description given in the question. It has lateral branches that grow underground and then emerge to form new leafy shoots.
