Depolarizes
The process by which a cell’s electrical charge becomes less negative, often initiating a nerve impulse or muscle contraction.
Neurotransmitter
Chemical messengers that transmit signals across a synapse from one neuron to another.
Taste Cell
A type of cell found in the taste buds that is responsible for sensing taste stimuli.

Final Answer :
B
Explanation :
The correct sequence for tasting starts with the food substance dissolving in saliva (3), then the substance enters the taste pore and attaches to a receptor on the taste hair (5), leading to the depolarization of the taste cell (1). This depolarization causes the release of neurotransmitters by the taste cell (4), which finally stimulates an action potential in the sensory neuron associated with the taste cell (2).
