2.It is highly social animal due to high levels of encephalisation.
3.It is categorized as critically endangered by the IUCN.
How many of the above statements are correct?
Answer: A
Notes:
Explanation: Only 2
Statement 1 is incorrect: Orcinus orca is a dolphin in the family Delphinidae, not a true whale, and it is the most widely distributed of all cetaceans. It is commonly called as the killer whale.
Statement 2 is correct: It is highly social. It often approaches fishing vessels to check nets or observe people. This behavior is due to high levels of encephalisation, meaning a larger brain size relative to the size of the body.
Statement 3 is incorrect: Conservation status: Data Deficient (IUCN).
