Final answer:
Option (2), Australopithecus anamensis had a small brain, large canines, and a projecting face, indicative of the gracile australopithecines.
Step-by-step explanation:
Australopithecus anamensis is known to be one of the gracile australopithecines. It had a small brain similar to that of a modern chimpanzee, large canines, and a projecting face with pronounced prognathism. Based on the evolutionary trends observed in the australopithecine species such as Australopithecus afarensis, which had smaller canines and a reduced dentition compared to apes, it is reasonable to infer that A. anamensis also had larger teeth than modern humans, but not as large as those found in earlier apes.
The correct traits for Au. anamensis from the list provided are a small brain, large canines, and a projecting face (option 2). It represents the combination of characteristics that were typical of early hominids before the appearance of the genus Homo, which started to show a rounder, globular skull, and reduced jaw and tooth size.
