Select the pseudocoelomtates from the list of organism given below.

Options

A. Ascaris, Fasciola, Taenia
B. Culex, Locusta, Limulus
C. Wuchereria, Ascaris, Ancylostoma
D. Nereis, Hirudinaria, Wuchereria

Answer

To solve the question of selecting the pseudocoelomates from the given list of organisms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Pseudocoelomates**: These are organisms that have a body cavity (coelom) that is not completely lined by mesoderm. They are typically found in the phylum Nematoda (roundworms).
- **True Coelomates**: These organisms have a body cavity that is completely lined by mesoderm.
- **Acoelomates**: These organisms lack a body cavity.

2. **Analyze the Options**:
- **Option A**: Ascaris, Fasciola, Taenia
- Ascaris belongs to Nematoda (pseudocoelomate).
- Fasciola and Taenia belong to Platyhelminthes (acoelomates).
- **Option B**: Culex, Locusta, Limulus
- All belong to Arthropoda (true coelomates).
- **Option C**: Vuchereria, Ascaris, Ancylostoma
- Vuchereria and Ascaris belong to Nematoda (pseudocoelomates).
- Ancylostoma also belongs to Nematoda (pseudocoelomate).
- **Option D**: Nereis, Herudinaria, Vuchereria
- Nereis and Herudinaria belong to Annelida (true coelomates).
- Vuchereria belongs to Nematoda (pseudocoelomate).

3. **Identify Pseudocoelomates**:
- From the analysis, the organisms that belong to the Nematoda phylum are the pseudocoelomates.
- In **Option A**, only Ascaris is a pseudocoelomate.
- In **Option B**, there are no pseudocoelomates.
- In **Option C**, all three organisms (Vuchereria, Ascaris, Ancylostoma) are pseudocoelomates.
- In **Option D**, only Vuchereria is a pseudocoelomate.

4. **Select the Correct Option**:
- The only option that contains exclusively pseudocoelomates is **Option C**: Vuchereria, Ascaris, Ancylostoma.

### Final Answer:
The pseudocoelomates from the given list of organisms are found in **Option C: Vuchereria, Ascaris, Ancylostoma**.
