Explanation:

The proximodistal principle of growth states that development proceeds from the center of the body outward. Grasping uses upper body/limb muscles closer to the torso, while walking uses lower body muscles farther from the core, so grasping develops first. The cephalocaudal principle refers to head-to-toe development, differentiation is about skill specialization, and plasticity is about brain adaptability, none of which fit this scenario.

Answer:

proximodistal
