Answer

To determine which type of fruit has a stony endocarp, we can analyze the characteristics of different fruit types mentioned in the video transcript.

### Step-by-Step Solution:

1. **Identify the Types of Fruits**: The video mentions four types of fruits: pepo, drupe (droop), pom, and berry.

2. **Understand the Structure of Fruits**: Each fruit has three parts of the pericarp:
- **Exocarp**: The outer layer.
- **Mesocarp**: The middle layer.
- **Endocarp**: The inner layer that surrounds the seed.

3. **Define Stony Endocarp**: A stony endocarp refers to a hard, non-edible inner layer that protects the seed.

4. **Examine Each Fruit Type**:
- **Pepo**: Example - Watermelon. The endocarp is not stony.
- **Drupe**: Example - Mango. The endocarp is stony and hard.
- **Pom**: Example - Apple. The endocarp is not stony.
- **Berry**: Example - Grapes. The endocarp is not stony.

5. **Conclusion**: Among the fruits listed, the drupe (specifically the mango) is the one that has a stony endocarp.
