Question

According to IUCN, some of the extinctions include:
• [(i)] Dodo
• [(ii)] Indian gazelle
• [(iii)] Thylacine
• [(iv)] Steller’s Sea Cow

• A. (i), (ii), (iii) and (iv)
• B. (ii) and (iv)
• C. (i), (iii) and (iv)
• D. (iii) and (iv)

Hint:

Remember the classic extinction list: Dodo (Mauritius), Quagga (Africa), Thylacine (Australia), Steller's Sea Cow (Russia). The Indian Gazelle is still alive and well!

Answer 1

The Correct Option is C

Concept: The International Union for Conservation of Nature (IUCN) maintains the Red List, which documents global species extinctions. According to standard conservation logs, several animal species have been driven to extinction by human activities over the last few centuries:
• Dodo (Raphus cucullatus): Extinct flightless bird from Mauritius.
• Thylacine: Extinct marsupial carnivore from Tasmania.
• Steller's Sea Cow (Hydrodamalis gigas): Extinct marine mammal from the North Pacific.
• Quagga: Extinct subspecies of zebra from Africa.
• Caspian, Javan, Bali tiger subspecies: Extinct large cats.

Step 1: Check the operational status of item (i), (iii), and (iv).
The Dodo (i), Thylacine (iii), and Steller’s Sea Cow (iv) are explicitly recorded as confirmed extinct species in recent history on the IUCN Red List.

Step 2: Check the operational status of item (ii).
The Indian gazelle (Chinkara) is currently an active, living wild animal found in the arid plains and deserts of India and Pakistan. It is classified under the "Least Concern" or "Vulnerable" regional parameters but is definitely not extinct.

Step 3: Combine valid extinct items.
Gathering our true points leaves us with (i), (iii), and (iv). This combination matches Option (C).
