Final answer:
Cro-Magnon individuals have traits characteristic of modern Homo sapiens, not Homo erectus, Neanderthals, or Australopithecus. Therefore, the correct trait for Cro-Magnon is Modern Homo sapiens characteristics.
Step-by-step explanation:
The traits of Cro-Magnon humans include characteristics associated with modern Homo sapiens. Cro-Magnon people, who appeared around 40,000 years ago, are considered to be an early subspecies of Homo sapiens. They are not associated with traits of Homo erectus, Neanderthals, or the Australopithecus-like skull.
Unlike the Australopithecus species, which had smaller brains and more prominent jaws, or Homo erectus, with its thick skull bones and pronounced brow ridges, Cro-Magnon had a larger brain and less pronounced facial features, similar to modern humans. Neanderthals, another archaic human species, also had distinguishing traits such as a larger skull and brain, prominent brow ridges, and a strong but differently shaped physique, thus these are not typical Cro-Magnon characteristics either.
Therefore, the correct answer to the question about the traits true about Cro-Magnon is C) Modern Homo sapiens characteristics.
