b. vegetarian (only, or almost entirely a plant diet)
c. omnivorous (both meat from hunted large animals and plant foods)
d. fish/aquatic foods

c. omnivorous (both meat from hunted large animals and plant foods).

Explanation:

The denture pattern of Australopithecians was like that of the modern humans but there were some specifications which suggests that these were omivorous. Like, the size of the teeth was large, molars were enormous and powerful. Their canines were small and their cheek teeth were larger than the modern humans. These characteristics suggests that they were capable of eating plant foods such as fruits, roots and also meat of other animals.
