Answer:
Correct Answer: B
Solution:
The sense of smell in mammals is very acute.
Unlike gustatory stimuli, the olfactory stimuli are produced by chemicals in gas from (odours) and in very small concentrations.
The gaseous molecules, entering the nasal chambers, dissolve in mucus covering the olfactory cells and stimulate them.
The olfactory sense is well developed in rabbits for locating foods, sensing enemies and searching mating partners.
