The correct option is C Taste buds
Taste cells on our tongue that receive stimulation of taste are known as taste buds.Taste buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper oesophagus, the cheek and epiglottis.These structures are involved in detecting the five elements of taste perception- salty, sour, bitter, sweet and umami. Umami is the savoury flavour found in protein-rich foods, such as meat, seafood, and cheese. It is also associated with monosodium glutamate (MSG) also called “hunching”, often used in Asian cuisine.
