Options

A. Sun-aerial stem
B. Underground stem
C. aerial stem
D. root

Answer

To solve the question regarding the type of vegetative propagule known as stolon, particularly in strawberries, we will analyze the options provided step by step.

### Step-by-Step Solution:

1. **Understanding Stolon**:
- A stolon is a type of vegetative structure that allows plants to propagate asexually. It is typically a horizontal stem that grows along the ground.

2. **Analyzing the Options**:
- **Option 1: Sub-aerial Stem**:
- Sub-aerial stems are stems that grow above the ground but do not rise significantly. They can spread horizontally and are capable of producing new plants at nodes. This matches the description of a stolon.
- **Option 2: Underground Stem**:
- Underground stems, such as tubers or rhizomes, grow below the soil surface. This does not match the characteristics of a stolon, which grows above the ground.
- **Option 3: Aerial Stem**:
- Aerial stems grow vertically above the ground and do not spread horizontally. This option is incorrect as it does not describe the stolon.
- **Option 4: Root**:
- Roots are part of the plant that typically anchor it and absorb water and nutrients. They do not serve the same purpose as stolons and are not modified stems.

3. **Conclusion**:
- Based on the analysis, the correct answer is **Option 1: Sub-aerial Stem**. This is because stolons are modified stems that grow horizontally above the ground, which is characteristic of sub-aerial stems.

### Final Answer:
**Stolon is a type of vegetative propagule which is majorly observed in strawberries. It is a modified sub-aerial stem.**
