Final answer:
The rooting reflex is the neonatal reflex most closely associated with feeding as it helps the infant locate the nipple and begin sucking.
Step-by-step explanation:
The neonatal reflex most closely related to feeding is the rooting reflex. This reflex is vital for an infant's survival as it helps the baby find the nipple to feed. When an infant's cheek is stroked, the rooting reflex causes the baby to instinctively turn its head toward the touch and start sucking.
This reflex ensures that the infant can feed effectively from a mother's breast or a bottle as soon as it is born. The other reflexes like the Moro reflex, the Babinski reflex, and the grasp reflex, although important for development and survival, are not directly related to feeding.
