Options

A. Brunner's glands and leaf like villi
B. Brunner's glands and peyer's patches
C. Club-shaped villi and Peyer's patch
D. Peyer's patches and Brunner's glands

Answer

### Step-by-Step Solution:

1. **Understanding the Ileum**: The ileum is the final part of the small intestine, following the duodenum and jejunum. It plays a crucial role in the absorption of nutrients, particularly vitamin B12 and bile salts.

2. **Identifying Key Features**: The ileum is characterized by specific structures that aid in its function:
- **Villi**: These are finger-like projections that increase the surface area for absorption. The more surface area available, the more nutrients can be absorbed.
- **Peyer's Patches**: These are clusters of lymphatic tissue found in the ileum that monitor intestinal bacteria and prevent their overgrowth.

3. **Analyzing the Options**: The question provides several options that include combinations of Brunner's glands, villi, and Peyer's patches.
- Brunner's glands are actually located in the duodenum, not the ileum.
- The ileum is characterized by the presence of villi and Peyer's patches.

4. **Conclusion**: The correct answer to the question "Ileum is characterized by" is **Peyer's patches and villi**.

### Final Answer:
The ileum is characterized by **Peyer's patches and villi**.
