Answer

To solve the question "Hydra possesses," we need to analyze the reproductive structures of Hydra and determine the correct option based on its reproductive system.

### Step-by-Step Solution:

1. **Understanding Hydra's Reproductive System**:
- Hydra is a genus of small, freshwater organisms that belong to the phylum Cnidaria.
- They are known to be hermaphroditic, meaning they have both male and female reproductive organs.

2. **Identifying the Reproductive Structures**:
- Hydra possesses testes and ovaries.
- Testes are responsible for producing sperm, while ovaries produce eggs (oocytes).

3. **Analyzing the Options**:
- **Option 1**: "1 testis and 1 ovary" - This implies that Hydra has one of each, which is not accurate since they can have multiple reproductive structures.
- **Option 2**: "1 testis and many ovaries" - This is incorrect because Hydra does not have multiple ovaries.
- **Option 3**: "Many testes and many ovaries" - This is also incorrect as Hydra does not possess multiple ovaries.
- **Option 4**: "Many testes and 1 ovary" - This option is correct as Hydra can have multiple testes producing sperm and typically has one ovary producing eggs.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option 4: Many testes and 1 ovary**.
