Solution

The correct option is B Cynodon
Invasive alien species are non- native organisms that may get incorporated into a foreign ecosystem and compete for habitat, food etc with the native species, many a times threatening the existance of the native species. Lantana is native to tropical regions of America and Africa. Parthenium was introduced in India as a contaminant with Wheat. Eichhornia was introduced for its beautiful foliage and flowers from South America, which has now become a weed covering the entire surface of the water body and preventing the growth and development of organisms below.
Cynodon is found in various trophical regions including India hence, it is not an alien species.
So, the correct answer is 'Cynodon'
