Solution

The correct option is C spinal cord
The spinal cord is responsible for reflex actions. These are actions that need quick response in times of danger. The feeling of heat does not need to travel all the way to the brain to wait for a response. The spinal cord quickly gives a sign to pull back the hand immediately once the hot cup is touched. Thus, the spinal cord gives the first and immediate response in case of danger.
