• D. Lantana is popularly known as carrot grass

Answer 1

Answer: (C)

Steller's sea cow (from Russia) is a recently extinct animal.
Parthenium (carrot grass) is an exotic weed, which grows rapidly and adversly affects the native species.
African catfish is also an alien species which adversly affects the growth of indigenous Clarias batrachus - our local species.
Lantana camara, another alein species, is also strongly competing with native species.
