Adinandra griffthii
Aglaia perviridis

  • A.All have been extinct.
  • B.All are gymnosperms.
  • C.All are identified as endangered species.
  • D.All are angiosperms.

Answer: C

The four names are Abies delavayi, Aconitum diennorrhizum, Adinandra griffithii and Aglaia perviridis, plants of the Indian Himalayan and north-eastern region that appear on lists of endangered species, so the common feature is that all are identified as endangered. They cannot all be gymnosperms or all angiosperms, because Abies is a conifer (gymnosperm) while Aconitum, Adinandra and Aglaia are flowering plants (angiosperms). They are not extinct, since they are still recorded in the wild.
