Question Detail

This is a confusing question. Peking man (Homo erectus pekinensis) is an extinct subspecies of Homo erectus. 'Lucy' is the common name for a fossil of Australopithecus afarensis, a much earlier hominin. Peking man did not 'originate' from any of these options in a simple way. Perhaps the question means which is an early hominin? Or it might be based on a specific textbook. 'Lucy' is a famous early hominin ancestor. Given the options, 'Lucy' is the most ancestral. This is a poorly constructed question. I'll go with D as the most likely intended answer.
