Animals with self fertillization is

Options

A. paragonimus
B. Dugesia
C. Taenia solium
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding Self-Fertilization**: Self-fertilization is a reproductive process where an organism can fertilize its own eggs with its own sperm. This is common in certain hermaphroditic organisms, which possess both male and female reproductive organs.

2. **Identifying the Organism**: The question specifically asks for an animal that undergoes self-fertilization. One well-known example of such an organism is *Taenia solium*, commonly known as the pork tapeworm.

3. **Reproductive Process in *Taenia solium***: In *Taenia solium*, both self-fertilization and cross-fertilization can occur. Self-fertilization happens when the sperm produced by the same proglottid (segment of the tapeworm) fertilizes the eggs produced in that same segment.

4. **Distinguishing Self-Fertilization from Cross-Fertilization**:
- In self-fertilization, the sperm and eggs come from the same individual, leading to the fertilization of the ova by its own sperm.
- In contrast, cross-fertilization involves the sperm from one individual fertilizing the eggs of another individual of the same species.

5. **Conclusion**: Therefore, the animal that exhibits self-fertilization is *Taenia solium*.
