Vegetative propagation in Eicchornia occurs by

Options

A. stolon
B. offset
C. runner
D. sucker

Explanation

**Step-by-Step Solution:**

1. **Understanding Vegetative Propagation**: Vegetative propagation is a form of asexual reproduction in plants where new individuals are produced from vegetative parts of the plant, such as stems, leaves, or roots, rather than from seeds.

2. **Identifying the Plant**: The question refers to the plant *Eichhornia*, commonly known as water hyacinth. It is an aquatic plant that is known for its rapid growth and beautiful flowers.

3. **Recognizing the Method of Propagation**: In *Eichhornia*, vegetative propagation occurs through structures known as offsets. Offsets are short lateral branches that arise from the main stem and can develop into new plants.

4. **Describing Offsets**: Offsets are typically one internode long and consist of a rosette of leaves and a tuft of roots. When an offset breaks off from the parent plant, it can grow into a new individual plant.

5. **Comparing with Other Plants**: Other plants like *Pistia* (water lettuce) also propagate in a similar manner using offsets. In contrast, other methods of vegetative propagation such as stolons (e.g., strawberries) or suckers (e.g., mint) do not apply to *Eichhornia*.

6. **Conclusion**: Based on the information, the correct answer to the question is that vegetative propagation in *Eichhornia* occurs by offsets.

**Final Answer**: Vegetative propagation in *Eichhornia* occurs by offsets.
