Options

A. Extra secretion of digestive enzymes
B. Increasing absorptive area
C. Slowing down passage of food
D. Crushing of food

Answer

**Step-by-Step Solution:**

1. **Understanding Typhosole**: The typhosole is a structure found in the intestine of earthworms. It is a fold of the dorsal wall of the intestine.

2. **Location of Typhosole**: The typhosole is present in the intestine starting from the 26th segment of the earthworm's body.

3. **Function of Typhosole**: The primary function of the typhosole is to increase the surface area available for absorption. This is crucial because it allows for more efficient nutrient uptake from the digested food.

4. **Eliminating Incorrect Options**:
- The typhosole does not secrete digestive enzymes; this function is performed by other parts of the digestive system.
- It does not slow down the passage of food; rather, it facilitates absorption.
- Crushing of food occurs in the mouth, not in the intestine where the typhosole is located.

5. **Conclusion**: Therefore, the correct answer to the question is that the typhosole of the earthworm is a device for increasing the absorptive area.

**Final Answer**: The typhosole of the earthworm is a device for increasing absorptive area.
