Answer

To solve the question regarding the dry indehiscent single-seeded fruit formed from a bicarpillary syncarpous inferior ovary, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Dry Indehiscent Fruit**: This type of fruit does not split open at maturity to release seeds.
- **Single-Seeded Fruit**: This indicates that the fruit contains only one seed.
- **Bicarpillary Syncarpous Ovary**: This means the ovary is formed from two carpels that are fused together.
- **Inferior Ovary**: This indicates that the ovary is located below the attachment of other floral parts.

2. **Identify Possible Fruit Types**:
- We need to identify fruits that are dry, indehiscent, single-seeded, and formed from a bicarpillary syncarpous inferior ovary.

3. **Evaluate the Options**:
- **Caryopsis**: This is a dry, single-seeded fruit where the ovary wall is fused with the seed coat. However, it does not fit the criteria of being formed from a bicarpillary syncarpous inferior ovary.
- **Sepsila**: This fruit is indeed a dry, indehiscent, single-seeded fruit formed from a bicarpillary syncarpous inferior ovary. It is typically found in the family Asteraceae (composites).
- **Berry**: This is a fleshy fruit and does not fit the criteria of being dry and indehiscent.
- **Cremocarp**: This is a type of dry, dehiscent fruit, which does not fit the criteria of being indehiscent.

4. **Conclusion**:
- The correct answer to the question is **Sepsila**, as it meets all the specified characteristics: it is a dry indehiscent single-seeded fruit formed from a bicarpillary syncarpous inferior ovary.

### Final Answer:
The dry indehiscent single-seeded fruit formed from a bicarpillary syncarpous inferior ovary is **Sepsila**.
