Rugae- Mucosal folds in stomach which unfold and let the stomach expand to accommodate a large meal.
Haustra- Small pouches in the wall of colon which may evaginate in elderly to become diverticula.

A. Only I
B. Only II
C. I and II
D. Only III

Answer

To identify the incorrect matches from the provided statements, we will analyze each term and its definition one by one.

### Step 1: Analyze the term "Rugae"
- **Definition**: Rugae are the mucosal folds in the stomach that unfold to allow the stomach to expand when it fills with food.
- **Match**: The statement about Rugae is correct.

### Step 2: Analyze the term "Haustra"
- **Definition**: Haustra are small pouches in the wall of the colon. They are formed by the contraction of the colon and can become diverticula in elderly individuals if they evaginate.
- **Match**: The statement about Haustra is also correct.

### Step 3: Analyze the term "Villi"
- **Definition**: Villi are small, finger-like projections in the mucosa of the small intestine that increase surface area for absorption. While they are primarily associated with the small intestine, they can also be found in the large intestine, but they are not as prominent.
- **Match**: The statement about Villi is misleading. Villi are not typically found in the walls of the large intestine in significant numbers as they are in the small intestine. Therefore, this match is incorrect.

### Conclusion
The incorrect match is:
- **Villi – Mucosa projection in walls of large intestine which contain blood vessels and lacteals that receive products of digestion.**

### Final Answer
The incorrect match is "Villi".
