For the absorption of digestive material, structures present in epithelium of digestive tract are
(a) zymogenic granules
(b) microvilli
(c) Peyer's patches
(d) none of these

Options

A. zymogenic granules
B. microyilli
C. Peyer's patches
D. none of these

Explanation

To solve the question regarding the structures present in the epithelium of the digestive tract that are responsible for the absorption of digestive material, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which structures in the epithelium of the digestive tract are involved in the absorption of digestive materials.

2. **Analyzing the Options**:
- **(a) Zymogenic granules**: These are involved in the secretion of digestive enzymes but do not play a direct role in absorption.
- **(b) Microvilli**: These are tiny, finger-like projections on the surface of epithelial cells in the intestines that increase the surface area for absorption.
- **(c) Peyer's patches**: These are lymphoid tissues found in the intestine that are involved in immune response, not directly in absorption.
- **(d) None of these**: This option suggests that none of the provided options are correct.

3. **Identifying the Correct Answer**: Among the options, microvilli (option b) are specifically designed to enhance the absorption of nutrients by increasing the surface area of the intestinal lining.

4. **Conclusion**: Based on the analysis, the correct answer is **(b) microvilli**.

### Final Answer:
(b) microvilli
