The correct option is A Taste buds of tongue
The gustatory system creates the human sense of taste, allowing us to perceive different flavors from substances that we consume as food and drink. Gustation, along with olfaction (the sense of smell), is classified as chemoreception because it functions by reacting with molecular chemical compounds in a given substance. Specialized cells in the gustatory system that are located on the tongue are called taste buds, and they sense tastants(taste molecules). The taste buds send the information from the tastants to the brain, where a molecule is processed as a certain taste.
