The stimulation of sensory receptors in the foot will trigger the withdrawal reflex, causing the foot to be pulled away from the sharp object. This reflex is mediated by interneurons in the spinal cord, which synapse with both sensory and motor neurons to produce a rapid and automatic response. The sensation of pain is also produced by the sensory neurons, which transmit the information to the brain for further processing. Therefore, option B is the best choice as it accurately describes the immediate response to stepping on a sharp tack.
