Answer: Option C) part of the tongue that is stimulated
Explanation:
On touching a substance, the nerve ending of the tongue is stimulated. The impulses are transmitted through the sensory neuron into the brain. From there, impulses are relayed to the intermediate neuron and then goes to the effector organ which brings about an interpretation of strength of the taste sensation
Thus, the strength of taste sensation depends on the part of the tongue that is stimulated.
