anonymous · Answer

The answer would be B. A large jaw bone can only prove on how a living organism adapted to eating large quantities of food. Very Long arms doesen't seem to be a great answer because alot of animals have long arms. Thick rib cage doesen't prove to be knowingly human either. It's also shown in anatomy that the pelvic bone is inward anyway :)
