Lantana camara, water hyacinth
B
water hyacinth, Prosopis cineraria
C
Nile perch, Ficus religiosa
D
Ficus religiosa, Lantana camara
Detailed Solution
An exotic (alien) species is a species that has been introduced from another geographical region into an area outside its natural range.
Lantana camara is native to tropical America and was introduced into India; it has become an invasive weed.
Water hyacinth (Eichhornia crassipes) is native to South America and was introduced into India for its beautiful flowers; it now clogs water bodies and is called the 'terror of Bengal'.
So Lantana camara and water hyacinth are both exotic species introduced in India.
Prosopis cineraria (khejri) and Ficus religiosa (peepal) are native Indian trees.
The Nile perch is an exotic fish, but it was introduced into Lake Victoria in East Africa, not into India.
So the correct pair is Lantana camara and water hyacinth.
