Triops commonly multiplies through

Options

A. Sexually
B. Asexually
C. Parthenogenetically
D. All the above.

Answer

### Step-by-Step Solution:

1. **Understanding Reproductive Methods**:
- **Asexual Reproduction**: Involves one parent, producing genetically identical offspring.
- **Sexual Reproduction**: Involves two parents, resulting in genetically unique offspring.
- **Parthenogenesis**: A form of asexual reproduction where an egg develops into an embryo without fertilization.

2. **Identifying the Organism**:
- Triops is a genus of small crustaceans commonly referred to as tadpole shrimp. They are known for their ancient lineage and are often called living fossils.

3. **Determining the Common Method of Multiplication**:
- Research indicates that triops primarily reproduce through parthenogenesis, where the female can produce offspring without the need for male fertilization.

4. **Conclusion**:
- Based on the understanding of the reproductive methods and the specific characteristics of triops, the correct answer to the question is that triops commonly multiplies through **parthenogenesis**.

### Final Answer:
Triops commonly multiplies through **parthenogenesis**.
