Final answer:
The earliest hominids originally lived in Africa before migrating and settling in parts of Asia and Europe, so the correct answer is A) Africa, Asia and Europe.
Step-by-step explanation:
The earliest hominids lived in Africa. Hominins, which are early human ancestors, began their journey within Africa and as they evolved, some species migrated to other continents. Australopithecus, an early hominin, is one significant example of early hominids that evolved in eastern Africa around four million years ago. As evolution progressed, the emergence of Homo erectus around 1.89 million years before the present marked a significant point in human migration, with these hominins expanding their territories beyond Africa and into Asia and Europe. Therefore, the answer to the student's question is: A) Africa, Asia and Europe.
