The right option is; pelvis rotated inward
Bipedalism is a type of terrestrial locomotion in which an organism moves by using its two legs or feet. Running, standing, walking, or jumping are the types of bipedal movement . Organisms that use this type of locomotion include humans, chimpanzees, pangolins, spider monkeys, kangaroo rats and mice, and capuchins. The inward rotation of the pelvis makes bipedalism possible.
