Scant scalp hair.
The Correct Answer is C
Choice A rationale

Correct Answer is D
Explanation
Choice A rationale
Stretching arms out and then back in is a common reflex in newborns known as the Moro reflex. It is not a sign of feeding readiness but rather a response to a sudden loss of support or a loud noise.
Choice B rationale
Turning the head toward a parent’s voice is a sign of auditory recognition and bonding, not necessarily feeding readiness. It indicates the infant’s ability to recognize familiar sounds.
Choice C rationale
Grasping a parent’s finger when placed in the infant’s palm is a primitive reflex known as the palmar grasp reflex. It is not related to feeding readiness but is a normal reflexive action in newborns.
Choice D rationale
Bringing their hand to their mouth is a sign of feeding readiness. This action indicates that the infant is hungry and ready to feed. It is an early cue that the baby is ready to eat.
