- Clarias gariepinus
- Eichhornia crassipes
- Parthenium
- Commelina benghalensis
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Some invasive species spread rapidly and disrupt ecosystems, earning specific common names.
Step 1: Identify "Terror of Bengal". Eichhornia crassipes (water hyacinth) is known as the “Terror of Bengal” because:
• It grows very rapidly in water bodies
• Forms dense mats on water surface
• Blocks sunlight and reduces oxygen levels
• Harms aquatic life and water transport
Step 2: Analyze options.
• (A) Clarias gariepinus → Fish species $\times$
• (B) Eichhornia crassipes → Water hyacinth \checkmark
• (C) Parthenium → Congress grass $\times$
• (D) Commelina benghalensis → Dayflower $\times$
Step 3: Conclusion. \[ \text{Terror of Bengal = Eichhornia crassipes} \]
