Answer

To solve the question "Which of the following is false about villi?", we will analyze each option provided in the question step by step.

### Step 1: Analyze Option A
- **Statement**: "They are small finger-like folding in the small intestine."
- **Truth**: This statement is true. Villi are indeed small, finger-like projections found in the lining of the small intestine, which help increase the surface area for absorption.

**Hint**: Consider the structure and location of villi in the digestive system.

### Step 2: Analyze Option B
- **Statement**: "They are supplied with a rich network of blood capillaries."
- **Truth**: This statement is also true. Villi contain a rich network of blood capillaries that facilitate the absorption of nutrients into the bloodstream.

**Hint**: Think about how nutrients are transported after absorption in the intestines.

### Step 3: Analyze Option C
- **Statement**: "They are supplied with a large length capillaries called Lacteals."
- **Truth**: This statement is partially misleading. Villi do contain lacteals, which are lymphatic capillaries that absorb fats, but they are not referred to as "large length capillaries." The term "large length" is not typically used to describe lacteals.

**Hint**: Recall the role of lacteals in fat absorption and their anatomical characteristics.

### Step 4: Analyze Option D
- **Statement**: "They have numerous microvilli which give the appearance of ciliated epithelium."
- **Truth**: This statement is false. While villi do have microvilli that increase the surface area for absorption, they do not give the appearance of ciliated epithelium. Microvilli are much smaller and do not resemble cilia.

**Hint**: Consider the differences between microvilli and cilia in terms of structure and function.

### Conclusion
After analyzing all the options, we find that the false statement about villi is **Option D**.

### Final Answer
**Option D** is the false statement regarding villi.
