Answer: (B)

Water hyacinth

Answer 2

The correct answer is water hyacinth.

One of the most pervasive weeds is the aquatic plant known as "water hyacinth," which may grow everywhere there is standing water. It depletes the water's oxygen, which causes other aquatic life to perish. It spreads quickly throughout the water body and may reproduce vegetatively at an incredible rate, making it incredibly challenging to eradicate.

Any aquatic plant belonging to the genus Eichhornia in the family of pickerelweeds (Pontederiaceae), has roughly five species and is largely indigenous to tropical America. Some species are rooted to muddy stream banks and lakeshores, while others float in shallow water. They all feature thin rootstocks, feathery roots, stalked leaf rosettes, and a few to many blooms grouped in spikes or clusters in the leaf axils.

The most prevalent species is the common water hyacinth (E. crassipes). The top lobes of the purple blooms contain blue and yellow patterns, and their leafstalk is puffy and spongy. It swiftly reproduces and frequently clogs slow-moving streams. In outdoor swimming pools and aquariums, it is utilized as an adornment.
