Final answer:
To classify the hominin fossil, the group must consider the characteristics and criteria used to differentiate between the Homo and Australopithecus groups. option c.
Step-by-step explanation:
When examining the characteristics of the hominin fossil, the group must determine which traits belong to the Homo group and which belong to the Australopithecus group. To assign a scientific name (genus/species), the group should consider the criteria used to differentiate between the two groups. Characteristics such as cranial capacity, dental features, and limb proportions can be used to determine the placement of the fossil into either group. For example, if the fossil has a larger cranial capacity and more advanced dental features, it would likely be classified within the Homo group. By considering these criteria, the group can determine the appropriate scientific name for the fossil.
