The correct option is D Homo habilis
Homo habilis, the first species of the genus Homo had a cranial capacity of about 600cc. However, it was much larger than that of Australopithecus. The cranial capacity of Homo erectus had increased to about 1100 cc and reached a maximum of 1500cc in Homo neanderthalensis. Homo sapiens have a cranial capacity of 1300cc, which is smaller than that of Homo neanderthalensis.
