Final answer:
The Moro reflex is an instinctive response true to infants, occurring when they feel as though they are falling. This reflex involves spreading out their arms and then bringing them back in, often with crying. The grasping reflex is a separate infant reflex, where they instinctively grasp objects placed in their hands.
Step-by-step explanation:
The statement about the Moro reflex being a movement where an infant moves their arm out as if frightened when released is true. This reflex is present in infants from birth until about three or four months of age. When an infant experiences a sudden loss of support, as if they are falling, the Moro reflex is triggered. The response involves the infant spreading its arms out, then pulling them back in, and often is accompanied by crying. By contrast, the grasping reflex is when a baby will instinctively grasp a finger or object placed in its palm, which aids in maintaining close physical contact with a caregiver.
As for the given options, Example A, which is about a neuron receiving touch information and controlling arm muscle movement, describes a basic neural reflex arc but is not directly related to the typical developmental reflexes seen in infants, such as the Moro or grasping reflexes.
