Explanation:
Detailed explanation-1: -Blinking of eyes is not a reflex action, but it is involuntary action. A reflex action is one which occurs spontaneously whereas involuntary action happens without the conscious choice of an organism.
Detailed explanation-2: -For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a “Hey, this is hot!” message even gets to your brain. Other protective reflexes are blinking when something flies toward your eyes or raising your arm if a ball is thrown your way.
