Studies have shown that by 6 months of age, infants display a smoother and more efficient reaching movement when using their right arm compared to their left arm. This is known as the "right-arm bias" and is believed to be linked to the development of language and cognitive processing in the left hemisphere of the brain. Therefore, the correct choice is C (reaching; right; left arm).
