An acoelomate animal with bilateral symmetry is

Options

A. Jelly Fish
B. Liver Fluke
C. Pleurobrachia
D. Ancylostoma

Answer

To solve the question "An acoelomate animal with bilateral symmetry is", we will analyze the options provided and determine which one fits the criteria of being an acoelomate and exhibiting bilateral symmetry.

### Step-by-Step Solution:

1. **Understanding Acoelomate Animals**:
- Acoelomate animals are organisms that lack a coelom, which is a fluid-filled body cavity. They typically have three tissue layers: ectoderm, mesoderm, and endoderm.

2. **Understanding Bilateral Symmetry**:
- Bilateral symmetry means that the organism can be divided into two equal halves along a single plane, resulting in left and right sides that are mirror images of each other.

3. **Analyzing the Options**:
- **Jellyfish**: Jellyfish are not acoelomate; they belong to the phylum Cnidaria and have radial symmetry.
- **Liver Fluke**: The liver fluke is a member of the phylum Platyhelminthes, which are known to be acoelomate and exhibit bilateral symmetry.
- **Plura Brachia**: This term does not correspond to a known acoelomate organism and is likely a misrepresentation or typo.
- **Encyclostoma**: This is a genus of parasitic roundworms (hookworms) that are pseudocoelomate, not acoelomate.

4. **Conclusion**:
- Among the options provided, the liver fluke is the only acoelomate animal that exhibits bilateral symmetry.

### Final Answer:
The correct answer is **Liver Fluke**.
