A
Correct answer
Explanation
The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened:
Vulnerable species
Endangered species
Critically endangered species
“Threatened” and “Extinct” are two completely different terms. Hence, option 4 is deleted. Considering this difference, you might have marked option 2 as the right answer.
