Answer

To determine which fruit has a hard and stony endocarp in the drupe category, we can analyze the options provided based on the characteristics of the endocarp.

### Step-by-Step Solution:

1. **Understanding Drupe Fruits**:
- A drupe is a type of fruit that has three layers: the exocarp (outer skin), mesocarp (fleshy middle), and endocarp (inner layer that surrounds the seed).
- The endocarp can be hard and stony in some drupe fruits.

2. **Identifying Fruits with Hard Endocarps**:
- We need to identify which of the provided fruits have a hard and stony endocarp.

3. **Analyzing Each Option**:
- **Mango (Mangifera indica)**:
- The endocarp of a mango is hard and stony, making it a true drupe.
- **Coconut (Cocos nucifera)**:
- The coconut also has a hard endocarp, which is the inner layer that surrounds the seed. Therefore, it is classified as a drupe.
- **Date Palm (Phoenix dactylifera)**:
- The endocarp of the date is soft and edible, not hard or stony.
- **Cucumber (Cucumis sativus)**:
- The cucumber does not have a hard endocarp; it is soft and fleshy.

4. **Conclusion**:
- The fruits with a hard and stony endocarp are **Mango (Mangifera indica)** and **Coconut (Cocos nucifera)**.
- Therefore, the correct answer to the question is both mango and coconut.

### Final Answer:
The endocarp is hard and stony in the drupe of **Mango (Mangifera indica)** and **Coconut (Cocos nucifera)**.
