Explanation:

Invasive weed Species :

Plants that do not occur naturally in a region but proliferate in the area they have been introduced into, and cause several negative impacts (such as affecting native biodiversity, causing economic losses and harming human health) in these new habitats, are called invasive plants.

Among these options of plant species We know;

• Lantana has become one of the world's most invasive weeds because of its high adaptability. Lantana (Lantana camara) has become one of the world's most invasive weeds.
• Parthenium hysterophorus is a serious invasive weed of pasture systems, reducing pasture productivity 90%.It has become a major weed of grazing lands in central Queensland and New South Wales in Australia.
• Water hyacinth reproduces vegetatively by off sets. It propagate, vegetatively, at an enormous and alarming rate. Therefore it spreads all over the water body and fully covers it within a short period of time. Thus, it has become the most invasive aquatic weed.

But in the case of Lotus ;

• It clogged water bodies including wetlands at many places resulting in death of several aquatic plants and animals. Therefore lotus is not an invasive species.
