The correct answer is option 2 - Endemic. An endemic species is a species that is found in a particular geographical area and is not naturally found anywhere else. It has a restricted distribution because it is unique to that specific region and cannot be found in other locations. This can be due to various factors such as geological isolation or evolutionary adaptations specific to that area. Endemic species are often of special interest to scientists and conservationists because they are more vulnerable to threats and have a higher risk of extinction compared to species with wider distributions. They can also provide important insights into the local ecological dynamics and evolutionary processes that have shaped the region`s biodiversity.
