Answer:
(B) were divided into hundreds of ethnic groups.
Step-by-step explanation:
The Aborigines are a group of Indigenous people inhabiting the Australian mainlands prior to its colonization by the British. They share similar genetic markers with the indigenous population of Papua New Guinea. The two groups, however, are distinct in their own ways, despite the similarity in physical features and cultural practices. One thing that the Aborigines and the Papuans have in common is that they both have many ethnic groups, each distinct in how they behave and function in the world.
