Taste receptor cells are clustered in taste bud which help in detecting taste like salty, sweet, bitter, sour and umami. Small openings called taste pores are present on the tongue epithelium. Food dissolved in saliva come into contact with the taste receptors through taste pores. Thus the correct answer is option B.
