The correct answer is C. They practiced ancestor workship and animism.
Explanation
Australian aborigines are the group of people who inhabited Australia from the Pleistocene until the Eighteenth Century when Europeans began to colonize the island. When the English arrived at the end of the 18th century, they found that there were about 500,000 aborigines, spread over concentrated nations mainly in the South and East of the country, most of them in the valley of the Murray River. Also, they were united by alliances, and each had developed its own customs. Each nation was made up of several clans whose number could vary from 5 to 40.
Regarding their religion, the Australian Aborigines practiced animism. Their gods were magnified magicians or super-men associated with the ocean, sky, fire, lava, and other natural phenomena. In addition, they were based on the ancestral myth about their creation and relationship with nature called Dreamtime. So the correct answer is C. They practiced ancestor worship and animism.
