Options

A. Small intestine
B. Large intestine
C. Colon
D. Stomach

Answer

**Step-by-Step Solution:**

1. **Understanding Villi**: Villi are small, finger-like projections that are found in certain parts of the digestive system. Their primary function is to increase the surface area for absorption.

2. **Location of Villi**: Villi are specifically located in the small intestine. This is crucial because the small intestine is the main site for nutrient absorption in the digestive system.

3. **Function of the Small Intestine**: The small intestine is responsible for the majority of nutrient absorption. The presence of villi enhances this process by providing a larger surface area, allowing for more efficient absorption of nutrients.

4. **Exclusion of Other Options**:
- The **large intestine** primarily absorbs water and electrolytes and does not have villi.
- The **colon** is part of the large intestine and also lacks villi.
- The **stomach** is mainly involved in the mechanical and chemical breakdown of food, and it does not absorb nutrients in the same way the small intestine does.

5. **Conclusion**: Based on the above points, the correct answer to the question "Where are villi present?" is the small intestine.

**Final Answer**: Villi are present in the small intestine.
