B. mosquito bite
C. drinking water containing eggs of Ascaris.
D. eating imperfectly cooked pork

Answer

**Step-by-Step Solution:**

1. **Understanding Ascaris**: Ascaris is a type of roundworm that causes a disease known as Ascariasis. It is important to know the mode of transmission of this parasite to answer the question correctly.

2. **Mode of Transmission**: The infection occurs when the eggs of Ascaris are excreted in the feces of an infected person. These eggs can contaminate water and food sources.

3. **Evaluating the Options**:
- **Option A: Cc Fly**: This option is incorrect. The Cc fly is known for transmitting sleeping sickness (trypanosomiasis), not Ascaris.
- **Option B: Mosquito Bite**: This option is also incorrect. Mosquito bites are associated with diseases like malaria, not Ascariasis.
- **Option C: Drinking Water Containing Eggs of Ascaris**: This is the correct option. The eggs can enter drinking water from the feces of infected individuals, leading to infection when ingested.
- **Option D: Eating Imperfectly Cooked Pork**: This option is incorrect as well. Eating undercooked pork can lead to trichinosis, not Ascariasis.

4. **Conclusion**: The correct answer to the question is that the infection of Ascaris usually occurs by drinking water containing eggs of Ascaris.

**Final Answer**: Option C - Drinking water containing eggs of Ascaris.
