The correct answer is A. In the Old Stone Age
Explanation:
The Homo habilis was a species of hominid that preceded the Homo Sapiens (modern humans); this specie originated around 2.3 million years ago and lived in groups. Besides this, the Homo habilis was one of the first species to create tools using stone; indeed, it was found Homo habilis selected and cut stones to use these to cut meat or even plants. This important technological advance occurred during the Old Stone Age or Early Stone Age, which refers to the first period in which hominids created stones that occurred between 2.6 million years ago and 10,000 years ago. Thus, the Homo habilis first began using tools in the Old Stone Age.
