Answer 2

We immediately withdraws ‘our hand’ on touching a very hot vessel due to Reflex action of our body.  

By this reflex action our brain and nervous system give us ability that if any part of our ‘body comes’ in contact with an object which can give us any harm or its temperature is very high then we tend to withdraw that part of our body quickly.

This immediate response can be termed as Reflex action of the human body.
