The correct option is B Eichhornia crassipes
Eichhornia crassipes, commonly known as water hyacinth, is an aquatic plant native to the Amazon basin. It is often considered a highly problematic invasive species outside its native range. When not controlled, water hyacinth will cover lakes and
ponds entirely; this dramatically impacts water flow, blocks sunlight from
reaching native aquatic plants, and starves the water of oxygen, often killing
fish and other aquatic animals. Hence option B is correct.
