Answer: B) The existence of marsupials such as kangaroos and koalas

Explanation: Marsupials are a family of mammals known for having a pouch to store their diminutive young as well as a variety of other biological features that sets them apart from other mammals. (such as their lack of a corpus callosum) Marsupials are native to Australia and the Americas, though the majority of marsupial species are native to Australia. (examples include kangaroos, koalas, and wombats) Thus, Australia's fauna is unique in that the majority of marsupial species call Australia their home.

Polar bears do not live in Australia. Rather, they reside in the Arctic Circle near the North Pole. Thus, they're found in Greenland and the northernmost areas of Russia and Canada.

African Elephants also do not live in Australia. As their name suggests, their native range are the savannahs of the continent of Africa.

The North American bison is also not found in Australia. As their name suggests, they're instead found in the grasslands of North America.
