Answer

To solve the question regarding the single-seeded indehiscent fruit having a stony endocarp, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Indehiscent Fruits**: These are fruits that do not split open at maturity to release their seeds.
- **Endocarp**: This is the innermost layer of the fruit wall, which surrounds the seed.

2. **Identify the Characteristics**:
- We are looking for a fruit that is both single-seeded and indehiscent.
- The fruit must also have a stony endocarp, which is a hard, stone-like layer surrounding the seed.

3. **Classify the Types of Fruits**:
- **Drupe**: A type of fruit that typically has a single seed enclosed in a hard endocarp (the stone). Examples include cherries, peaches, and almonds.
- **Achene**: A small, dry, indehiscent fruit that usually contains one seed but does not have a stony endocarp.
- **Nut**: A hard-shelled fruit that is also indehiscent but does not have the stony endocarp characteristic of drupes.

4. **Conclusion**:
- Based on the characteristics mentioned, the fruit that is single-seeded, indehiscent, and has a stony endocarp is a **drupe**.

### Final Answer:
The single-seeded indehiscent fruit having a stony endocarp is a **drupe**.
