Answer
Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern

The correct answer is Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern — Write the categories in the sequence: CR, EN, VU, NT, LC.

Step-by-step solution

  1. Recall that the IUCN Red List ranks species based on extinction risk.
  2. The highest risk among extant categories is 'Critically Endangered' (CR).
  3. Next comes 'Endangered' (EN), followed by 'Vulnerable' (VU).
  4. After the threatened categories, 'Near Threatened' (NT) indicates lower risk.
  5. Finally, 'Least Concern' (LC) represents the lowest risk among evaluated species.
  6. Write the categories in the sequence: CR, EN, VU, NT, LC.
Common mistake: Including 'Data Deficient' or 'Extinct' in the ordered list of living categories.
