The correct options are

There are basically four types of tastes. They are sweet, salt, sour and bitter. We detect different tastes of food at different regions of our tongue, since taste buds which find different tastes are located in different regions of the tongue. The taste buds for sweet are located in front; those for salt at anterior edges, those for sour at sides and those for bitter are located in the posterior region of the tongue.
