These lingual papillae are on the lateral sides of tongue:

1. Fungiform

2. Circumvallate

3. Foliate/Foliform

4. Filiform

The correct answer is: Foliate/Foliform

Lingual papillae are small raised bumps on the surface of the tongue. They are responsible for our sense of taste. The three types of papillae are fungiform, circumvallate, and foliate. Filiform papillae are not involved in taste sensation. They are small and spindle-shaped and present all over the tongue's surface, giving it the rough texture. They do not have taste buds. Circumvallate papillae are located on the back of the tongue in a V-shaped line. They are larger and flatter in shape compared to fungiform papillae. Fungiform papillae are spread across the tongue's surface and look like small red dots. They are also involved in taste sensation. However, the papillae described in this question are located on the lateral sides of the tongue, which are often referred to as the sides or edges of the tongue, and they are called foliate papillae. They are leaf-shaped and arranged in rows on the edges of the tongue towards the back. These papillae contain taste buds, but they are not as numerous as those on circumvallate and fungiform papillae. Therefore, the correct answer is C
