Final Answer :
D
Explanation :
Long curved toes and fingers suggest an adaptation for life in the trees (arboreal lifestyle), not bipedalism. Bipedalism is indicated by features such as a vertically oriented foramen magnum, a femur with a ball at its top for articulation with the pelvis, and a spine with a double curve for upright posture.
