In a negative feedback system, the stimulus is detected by sensory receptors, which send signals to the brain. The brain then processes this information and sends signals to effectors, which carry out a response to counteract the original stimulus. Therefore, the correct order is stimulus, sensory receptors, brain, effectors. Choice B is the only option that follows this order.
