Final Answer : B, Explanation :  Nociceptors are sensory receptors that respond to harmful or potentially damaging stimuli, such as heat, pressure, or chemicals. When these receptors are activated by such stimuli, they send neural signals to the brain, which are interpreted as the sensation of pain. Olfactory bulbs are involved in the perception of smell, while semicircular canals and vestibular sacs are involved in balance and spatial orientation, respectively.
