D
grasping
Explanation: 

Detailed explanation-1: -This reflex starts when the corner of the baby’s mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.

Detailed explanation-2: -In some cases, reflexes change into voluntary behavior. For example, your baby is born with a rooting reflex that prompts him to turn his head toward your hand if you stroke his cheek or mouth. This helps him find the nipple at feeding time.

Detailed explanation-3: -Your baby’s rooting reflex is an involuntary muscle response to stimulation of their mouth. It helps your baby find a nipple to feed. Your baby was born with this and other newborn reflexes to help them survive.

Detailed explanation-4: -The rooting reflex is one of the involuntary primitive motor reflexes, which are also known as the frontal release reflexes, that are mediated by the brainstem. It initiates when the corner of an infant’s mouth is stimulated.

Detailed explanation-5: -The rooting reflex is an innate response of the head due to the stimulation of the face, mouth, or cheek by touching/stroking (the head is turned towards the side of the stimulus). It is a brainstem mediated primitive motor reflex also called the frontal release reflex.
