  1. Parthenium is an endemic species of our country.

  2. African catfish is not a threat to indigenous catfishes.

  3. Steller's sea cow is an extinct animal.

  4. Lantana is popularly known as carrot grass.

Show answer
Correct Option: C
Explanation:

Steller's sea cow (Hydrodamalis gigas) is an extinct sirenian discovered by Europeans in 1741. At that time, it was found only around the Commander Islands in the Bering Sea between Alaska and Russia; its range was more extensive during the Pleistocene epoch, and it is possible that the animal and humans previously interacted. Some 18th-century adults would have reached weights of 8–10 t (8.8–11.0 short tons) and lengths up to 9 m (30 ft). Steller's sea cow was named after Georg Wilhelm Steller, a naturalist who discovered the species in 1741 on Vitus Bering's Great Northern Expedition when the crew became shipwrecked on Bering Island. Much of what is known about its behavior comes from Steller's observations on the island, documented in his posthumous publication On the Beasts of the Sea. Within 27 years of discovery by Europeans, the slow-moving and easily caught mammal was hunted into extinction for its meat, fat, and hide.

So the correct option is 'steller's sea cow is an extinct animal'.
