Answer

To determine the phylum to which Wuchereria bancrofti belongs, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Wuchereria bancrofti is a parasitic worm known for causing lymphatic filariasis in humans.

2. **Review the Options**: The options provided are:
- A) Nemathelmines
- B) Platyhelmines
- C) Nematoda
- D) Cnidaria (referred to as Selenthrata in the transcript)

3. **Analyze Each Option**:
- **Platyhelmines**: This group includes flatworms, which are triploblastic and bilaterally symmetrical. They are known for being acelomate (without a body cavity). Wuchereria bancrofti does not belong to this group.
- **Nemathelmines**: This term is often used interchangeably with Nematoda, which refers to roundworms. Wuchereria bancrofti is indeed a roundworm.
- **Nematoda**: This is the correct phylum for Wuchereria bancrofti. Nematodes are characterized by their cylindrical body shape and presence of a pseudocoelom.
- **Cnidaria (Selenthrata)**: This phylum includes organisms like jellyfish and corals, which are not related to Wuchereria bancrofti.

4. **Conclusion**: Based on the analysis, Wuchereria bancrofti belongs to the phylum **Nematoda** (also known as Nemathelmines).

### Final Answer:
Wuchereria bancrofti belongs to the phylum **Nematoda**.
