Select the incorrect statement w.r.t. Eichhornia

Options

A. Its propagation takes place by breaking of offsets.
B. It was introduced in Bengal because of its beautiful flowers and stems
C. It grows in stagnant water
D. Highly invasive aquatic weed referred as "Terror of Bengal"

Answer

To solve the question regarding the incorrect statement about Eichhornia (water hyacinth), we will analyze the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding Eichhornia**:
- Eichhornia, commonly known as water hyacinth, is an aquatic plant that floats on water surfaces. It is often referred to as a water weed due to its rapid growth and invasive nature.

**Hint**: Remember that Eichhornia is commonly known as water hyacinth and is considered an invasive species.

2. **Propagation by Offsets**:
- The first statement mentions that its propagation occurs by breaking of offsets. This is true because water hyacinth reproduces vegetatively through offsets, which are small daughter plants that grow from the main plant.

**Hint**: Offsets are a key feature of Eichhornia's reproductive strategy.

3. **Introduction to Bengal**:
- The second statement claims that it was introduced in Bengal for its beautiful flower and stem. This statement is incorrect because while it was indeed brought to India, it was not specifically introduced in Bengal for its beauty. It is often referred to as the "Terror of Bengal" due to its invasive nature and the ecological problems it causes.

**Hint**: Consider the ecological impact of Eichhornia when evaluating its introduction to new regions.

4. **Growth in Stagnant Water**:
- The third statement asserts that it grows in stagnant water, which is correct. Water hyacinth thrives in ponds, lakes, and other stagnant water bodies.

**Hint**: Eichhornia prefers still water environments for optimal growth.

5. **Invasive Nature**:
- The fourth statement indicates that it is an invasive aquatic plant and is known as the "Terror of Bengal." This is also true, as its rapid growth can lead to significant ecological disruption, affecting native aquatic species.

**Hint**: The term "Terror of Bengal" highlights the negative impact of Eichhornia on local ecosystems.

### Conclusion:
Based on the analysis, the incorrect statement regarding Eichhornia is the second one, which claims it was introduced in Bengal specifically for its beautiful flower and stem.

**Final Answer**: The incorrect statement is that it was introduced in Bengal for its beautiful flower and stem.
