Answer:
A. Sensory Neurons
The receptors receive the stimuli then it changes it to a signal or impulse. The neurons relay the impulse to their neighbor nerve cell until it reaches the brain. Brain receives the information through the sensory nerve cells. Information, in the form of nerve impulses, reaches the spinal cord through sensory neurons of the PNS. These impulses are transmitted to the brain through the interneurons of the spinal cord.
