D. All of these

Explanation

To determine which statement is incorrect, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement 1**:
- The statement claims that fecal accumulation in the rectum initiates a neural reflex causing the urge for its removal.
- **Explanation**: When feces enter the rectum, it stretches the rectal walls, triggering nerve signals to the central nervous system. This results in the urge to defecate, leading to the opening of the internal anal sphincter and the eventual expulsion of feces.
- **Conclusion**: This statement is **correct**.

2. **Analyze Statement 2**:
- The statement claims that irregular bowel movements cause constipation.
- **Explanation**: Irregular bowel movements, often due to inadequate peristalsis, lead to the retention of fecal matter in the intestines, which results in constipation.
- **Conclusion**: This statement is **correct**.

3. **Analyze Statement 3**:
- The statement claims that in diarrhea, absorption of food is increased.
- **Explanation**: Diarrhea is characterized by increased frequency and liquidity of bowel movements. This means that fecal matter is expelled quickly, reducing the time available for nutrient absorption in the intestines. Therefore, absorption is actually **decreased** during diarrhea.
- **Conclusion**: This statement is **incorrect**.

### Final Answer:
The incorrect statement is **Statement 3**: "In diarrhea absorption of food is increased."
