The correct answer is B.

According to the study of human evolution, the first individuals of the genus Homo evolved at approximately 7 million years ago. The general trend of their evolution included an increase of the skull (specifically the cranium) and subsequently the brain size. This, in turn, increased the brain capacity. In addition, hominids evolved to stand upright and walk with their two feet only, a phenomenon called bipedalism. Finally, they started developing and using tools.
