Solution

The correct option is B Eichhornia
Water hyacinth( Eichhornia crassipes) is known as the terror of bengal because it is an exotic shrub which strongly competes with the native species and has also eliminated many of them. It is a water-based plant that flourishes in the hot and humid climate of Bengal. Fish is a supplement food in Bengal. Water hyacinth is efficient in utilizing aquatic nutrients and solar energy for profuse biomass production and results in decline in number of fishes and because of the fish scarcity in Bengal caused by Eichhornia, the water hyacinth is also called "Terror of Bengal".
So, the correct option is 'Option B' .
