D. Drupe

Answer

To solve the question regarding a fruit that has differentiation of epicarp, mesocarp, and stony endocarp, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Fruits**:
- Fruits are formed from the ovary of a flower after fertilization. The ovary wall develops into the pericarp, which is the fruit wall.
- The pericarp is typically divided into three layers:
- **Epicarp (or Ectocarp)**: The outermost layer.
- **Mesocarp**: The middle layer, which is often fleshy.
- **Endocarp**: The innermost layer, which can be stony or hard.

2. **Identify the Types of Fruits**:
- Fruits can be classified into simple, aggregate, and multiple fruits.
- Simple fruits can further be categorized into fleshy and dry fruits. Fleshy fruits can be further divided into berries, drupes, and pomes.

3. **Focus on the Question**:
- The question specifies a fruit with differentiated epicarp, mesocarp, and stony endocarp. This indicates that we are looking for a specific type of fleshy fruit.

4. **Consider the Options Provided**:
- Option 1: Foam
- Option 2: Berry
- Option 3: Pepper
- Option 4: Drupe

5. **Analyze Each Option**:
- **Foam**: Not a recognized fruit type.
- **Berry**: Typically has a fleshy pericarp but does not have a stony endocarp.
- **Pepper**: A type of berry, also does not have a stony endocarp.
- **Drupe**: Characterized by having a fleshy outer layer (epicarp and mesocarp) and a hard, stony endocarp that surrounds the seed.

6. **Conclusion**:
- The fruit that has differentiation of epicarp, mesocarp, and stony endocarp is a **Drupe**.

### Final Answer:
The correct answer is **Drupe**.
