Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question refers to the housefly, which belongs to the family Diptera within the phylum Arthropoda.

2. **Understand the Mouthparts**: Houseflies have specialized mouthparts that are adapted to their feeding habits. These mouthparts are not designed for chewing or biting.

3. **Function of Mouthparts**: The mouthparts of houseflies are primarily used for sponging. They have a labium that is modified into a sponge-like structure at the end.

4. **Mechanism of Feeding**: Houseflies detect the presence of liquid food (like sugar) using chemosensilla located on their tarsi. Once they sense food, they secrete saliva that helps dissolve the food, making it easier to ingest.

5. **Process of Ingestion**: The liquid food is then soaked up and sucked through the mouthparts. The food enters the labium through small channels and moves into the esophagus.

6. **Conclusion**: Based on the structure and function of the mouthparts, it is clear that houseflies are specialized for sponging liquid food.

7. **Final Answer**: The correct option is A) sponging liquid food.
