Explanation

The question is asking about the groups of sensory cells found on the upper surface of the tongue. These cells are responsible for our ability to taste different flavors, and they are called taste buds. Therefore, the correct answer is option B. Taste buds are small clusters of cells found on the tongue, as well as the roof of the mouth and back of the throat. They contain specialized cells called gustatory cells, which are responsible for detecting different flavors. Taste buds can detect five basic tastes: sweet, sour, salty, bitter, and umami (savory). It's important to note that taste buds are not the only cells involved in our sense of taste. The process of tasting involves a complex interaction between taste buds, olfactory (smell) receptors, and other sensory cells. Our sense of taste is also influenced by factors such as texture, temperature, and even our emotional state. In conclusion, taste buds are the groups of sensory cells found on the upper surface of the tongue responsible for our sense of taste. They contain gustatory cells that detect different flavors, and work in conjunction with other sensory cells to create our sense of taste.
