D. diurnal rhythm

Answer

To solve the question "Which among these is associated with Ascaris?", we will analyze each option provided in the question and determine which one is specifically related to Ascaris.

### Step-by-Step Solution:

1. **Understanding Ascaris**: Ascaris is a type of roundworm that primarily lives in the intestines of humans. The disease caused by Ascaris is known as ascariasis.

2. **Analyzing the Options**:
- **Option A: Extra-intestinal migration**: This refers to the ability of Ascaris to migrate from the intestines to other parts of the body after maturation. This is a known characteristic of Ascaris, as it can cause symptoms like cough and abdominal discomfort due to its movement.
- **Option B: Nocturnal periodicity**: This term refers to the activity pattern of certain parasites that are more active at night. This is typically associated with filarial worms, not Ascaris.
- **Option C: Extra-intestinal amoebiasis**: This condition is caused by Entamoeba histolytica, a protozoan parasite, and is unrelated to Ascaris.
- **Option D: Diurnal rhythm**: This term describes the activity pattern of parasites based on the time of day, which is also associated with filarial worms, not Ascaris.

3. **Conclusion**: Based on the analysis, the only option that is directly associated with Ascaris is **Option A: Extra-intestinal migration**. This characteristic is significant in understanding the pathology of ascariasis.

### Final Answer:
The correct answer is **Option A: Extra-intestinal migration**.
