The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks for the plant that is commonly referred to as the "terror of Bengal." This requires knowledge of local flora and the impact of certain plants on the ecosystem. 2. **Identifying the Options**: The options provided include various aquatic plants. We need to evaluate each option to find the one that matches the description of "terror of Bengal." 3. **Analyzing the First Option - Water Lettuce**: Water lettuce is an aquatic weed and an invasive species, but it is not commonly known as the "terror of Bengal." 4. **Analyzing the Second Option - Echornia Crassipes**: This plant is scientifically known as water hyacinth. It is known to be invasive and has significant negative impacts on aquatic ecosystems. It blocks sunlight and reduces dissolved oxygen levels in water bodies, which can harm fish populations. 5. **Analyzing the Third Option - Hydrilla**: Hydrilla is also an aquatic plant that can pose threats to ecosystems by competing with native plants. However, it is not specifically referred to as the "terror of Bengal." 6. **Analyzing the Fourth Option - Vallisneria**: Vallisneria, known as eelgrass, is primarily used in aquariums and does not have the same negative ecological impact as the water hyacinth. 7. **Conclusion**: Based on the analysis, the plant that is commonly referred to as the "terror of Bengal" is indeed the water hyacinth (Echornia Crassipes). This plant's invasive nature and its detrimental effects on local aquatic life justify this nickname. **Final Answer**: The plant generally called "terror of Bengal" is the **water hyacinth (Echornia Crassipes)**. ---
