Solution

The correct option is B Spinal cord
Reflex action is a sudden and involuntary response to stimuli.
Pulling our hands away immediately after touching a hot or cold object is a classic example of a reflex action.
In a reflex action, the spinal cord along with the brain stem is responsible for reflex movements.
A few examples of reflex action are: When light acts as a stimulus, the pupil of the eye changes in size. Sudden jerky withdrawal of hand or leg when pricked by a pin.
So, the correct option is option B.
