without brain there would be no reflex. Spinal cord is just a carrier through neurons..it's the brain which signals to pull back the hand from a hot kettle...not any other organs.

The answer B is correct because the Spinal Cord controls the Reflex Actions and if we touch a hot kettle and move our hand back, its a Reflex Action of course!!!
