The Moro reflex, also known as the startle reflex, is demonstrated when an infant is startled by a loud noise or sudden movement. The infant will typically extend their arms, legs, and fingers and then quickly pull them back towards the body in a similar motion to an embrace. This reflex usually disappears after around 6 months of age. Option A (grasping) is demonstrated when an object is placed in an infant's palm, causing them to grasp it tightly. Option B (rooting) is demonstrated when an infant turns their head towards a touch on their cheek or mouth, in preparation for breastfeeding. Option C (Babinski) is demonstrated when an infant's foot is stroked, causing their toes to fan out and their big toe to move upward.
