Hermaphrodite animals are maximum in

Options

A. Annelida
B. Mammals
C. Nematoda
D. Arthropoda

Answer

### Step-by-Step Solution:

1. **Understanding Hermaphroditism**: Hermaphroditic animals possess both male and female reproductive organs within the same individual. This means they can produce both eggs and sperm.

2. **Identifying Phyla**: The question asks which phylum has the maximum number of hermaphroditic animals. We need to consider various phyla and their reproductive strategies.

3. **Analyzing Phylum Annelida**:
- The phylum Annelida includes organisms like earthworms and leeches, both of which are hermaphrodites.
- Earthworms have both male and female reproductive organs, allowing them to mate with any other earthworm.

4. **Comparing with Other Phyla**:
- In contrast, other phyla such as Nematoda (roundworms) and Arthropoda (insects, crustaceans) typically exhibit sexual dimorphism, meaning they have distinct male and female individuals.
- For example, in the case of cockroaches (Arthropoda) and Ascaris (Nematoda), males and females are separate.

5. **Conclusion**: Based on the information, the phylum with the maximum number of hermaphroditic animals is **Phylum Annelida**.

### Final Answer:
Hermaphrodite animals are maximum in **Phylum Annelida**.
