Explanation:

Species that are native to and restricted to a specific geographical area are known as endemic species. Their natural range is limited to that particular region, and they are not found elsewhere. Option (1) 'Endemic' is the correct term. Option (2) 'Rare' species have small population sizes, which may or may not be geographically restricted. Option (3) 'Endangered' species are those at a very high risk of extinction in the wild. Option (4) 'Threatened' species are likely to become endangered in the near future. While endemic species can also be rare, endangered, or threatened, the term 'endemic' specifically refers to their geographical confinement, regardless of their population status.
