Honeybees have an incredible ability to distinguish thousands of different odorant molecules, using their large repertoire of olfactory receptors. A wide variety of different types of chemicals can be detected as odorants; they simply require olfactory neurons with a receptor that can bind the chemical and transduce that stimulus into a receptor potential.Because small quantities of powerful explosives can be hidden easily, a sensor that could detect trace amounts of illicit chemicals would be a useful tool. What animal sensory modality is exquisitely sensitive to minute quantities of airborne chemicals?

A. Taste
B. Vision
C. Touch
D. Olfaction
E. Hearing
