Answer:
c. Filiform
Explanation:
The filiform papillae are pointed and threadlike in appearance. They are present on the surface of the tongue. The filiform papillae have tactile receptors and lack the taste buds. Since the filiform papillae lack taste buds, they do not serve in the reception of any taste. Rather, the function of filiform papillae is to help the tongue to move food in the mouth.
