Which of the following best defines a chemoreceptor?

Explanation:
Chemoreceptors are sensory cells or organs that detect chemical stimuli and convert those chemical signals into nerve impulses. That makes the best description a sensory cell/organ responsive to chemical stimuli, as it covers receptors in the nose for odors, the tongue for tastes, and internal chemoreceptors that monitor blood chemistry. Other receptor types respond to different physical modalities—light, touch, or temperature—rather than chemicals.
