The advantage of reflex action is - (c) it does not have to be learn.

•Reflex action is an involuntary or instantaneous action, performed by humans in response to stimulus.

•Reflex action is very important for humans.

•It is important because it saves children.

•Example - if a child touches the hot vessel, he will instantly take away his hand.

•The child can't be taught.

•This action protects him from burning his hand.
