The correct answer is C. A small population of bears who are the last members of their species
Step-by-step explanation:
In biology, the term "endangered species" is used to refer to animal or plant species likely to become extinct if no actions to increase the population of a species are taken. This means an endangered species is commonly one with a small population that tends to decrease over time and therefore this species might disappear in a near future, this includes species such as the Siberian tiger, the Asian elephant, and the mountain gorilla. Considering this, the one that would be an endangered species is "a small population of bears who are the last members of their species", because in this case, the population has reduced significantly and if it does not increase the species is likely to disappear in the future which occurs in endangered species.
