An example of a reflex action includes
A
Touching a butterfly
B
Brushing your hand against the side of your body
C
Touching a hot stove
D
Your legs moving as you walk
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -If you touch something that is very hot, your hand moves away quickly before you even feel the pain. You don’t have to think about it because the response is a reflex that does not involve the brain. A reflex is a rapid, unlearned, involuntary (automatic) response to a stimulus (change in the environment).

Detailed explanation-3: -Reflex arcs For example, a simple reflex arc happens if we accidentally touch something hot. Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS.

Detailed explanation-4: -Coughing, yawning and blinking of eyes are examples of reflex actions.

Detailed explanation-5: -For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race happens in an instant.
