Answer:
The correct answer is Marsupial.
Step-by-step explanation:
The word 'marsupial' originates from the Latin word "marsupium", which means 'pouch’. Most, but not all, female marsupials have a permanent pouch in which to raise their young. In the earlier times, Koalas were considered as bears by the Australians, this is the reason why they were called Koala Bears.
