Final answer:
At 5 months, a typical infant can transfer objects from one hand to the other, a developmental milestone that usually emerges around the age of 6 months.
Step-by-step explanation:
At 5 months, a typical infant can transfer objects from one hand to the other. This skill is part of the normal developmental milestones infants reach as they grow. Around six months of age, infants start to develop the ability to pick up objects and pass them from one hand to the other. This is a progression from earlier months where infants exhibit reflexive actions and simple motor skills, like the grasping reflex present at birth and described in a four-month-old infant, to more complex voluntary actions such as the hand-to-hand transfer.
While infants at 10 months begin to develop a pincer grasp and can sit unsupported, the milestone related to transferring objects from one hand to the other typically emerges around the six-month mark. Therefore, when considering the options provided in the question, the correct answer would be that a 5-month-old infant can transfer objects from one hand to the other. This milestone is indicative of growing motor skills and cognitive development that continues to advance as children grow.
