The normal sequence of structures for signal transmission and response in the body is that the receptor picks up the stimulus and sends a signal to the afferent neuron, which carries it to the interneuron. At this point, the signal is processed and integrated before being sent to the efferent neuron. The efferent neuron carries the signal to the effector, which responds accordingly. Therefore, the correct sequence is receptor, afferent neuron, interneuron, efferent neuron, and effector. Only option C follows this sequence, making it the best choice.
