Receptors sensitive to smell are
Correct answer: B. Chemical
- A. Mechanical
- B. Chemical
- C. Photoreceptors
- D. Georeceptors
Explanation
Receptors sensitive to smell are chemoreceptors, specifically olfactory receptors. These receptors detect chemical molecules in the air and translate them into neural signals that are processed as smells. Other types of receptors, such as mechanoreceptors, photoreceptors, and georeceptors, are specialized for detecting different types of stimuli: mechanical displacement, light, and balance, respectively.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
