Assertion `:` Products of digestion are absorbed in the small intestine.
Reason `:` Large intestine has impermeable wall.

Options

A. If both Assertion & Reason are True & the Reasonn is a correct explanation of the Assertion .
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Products of digestion are absorbed in the small intestine." This is true because the small intestine is specifically designed for absorption. It has a large surface area due to the presence of villi and microvilli, which facilitate the absorption of nutrients.

2. **Understanding the Reason**: The reason provided is "Large intestine has impermeable wall." This statement is misleading. While the large intestine does have a different function compared to the small intestine, it is not entirely impermeable. The large intestine primarily absorbs water and some electrolytes, which means it does allow for some absorption.

3. **Connecting Assertion and Reason**: The assertion and reason are related in that they both discuss the absorption process in the digestive system. However, the reason does not correctly support the assertion. The assertion focuses on the small intestine, while the reason incorrectly describes the large intestine's function.

4. **Conclusion**: Since the assertion is true (products of digestion are absorbed in the small intestine) and the reason is false (the large intestine is not impermeable and does absorb water), we conclude that the assertion is correct, but the reason is incorrect.

### Final Answer:
- The assertion is true, and the reason is false.
