Answer:
This reflex to fling their arms out and possibly cry is called Option A, the Moro reflex.
Step-by-step explanation:
You may notice that when your newborn is startled by something like a loud noise or a sudden movement, they react by extending their arms and legs wide and arching their back. They may cry or not cry when they do this. This is an involuntary response on the part of your baby to being startled called the Moro reflex. It is very common in newborns and it is something the baby will stop doing as they grow out of the newborn phase. Your doctor may try to check for the reflex in your first few checkups with your newborn.
