Answer

To determine the correct set of options regarding coconut, we will analyze the characteristics of coconut in terms of its structure and classification.

### Step-by-Step Solution:

1. **Identify the Scientific Name**:
- The scientific name of coconut is **Cocos nucifera**.

2. **Classify the Fruit Type**:
- Coconut is classified as a **drupe**. A drupe is a type of fruit that has a stony endocarp and is typically one-seeded.

3. **Understand the Layers of Coconut**:
- The coconut fruit consists of three layers:
- **Exocarp**: The outermost layer, which is green in young coconuts.
- **Mesocarp**: The fibrous layer beneath the exocarp, which is made of sclerenchyma fibers (commonly known as coir).
- **Endocarp**: The hard, stony layer that surrounds the seed.

4. **Identify the Edible Part**:
- The edible part of the coconut is the **endosperm**, which consists of two forms:
- **Liquid endosperm**: This is the coconut water.
- **Solid endosperm**: This is the white flesh of the coconut that we eat.

5. **Analyze the Options**:
- Based on the above information:
- The **mesocarp** is fibrous (made of sclerenchyma fibers).
- The **edible part** is the endosperm.
- The **endocarp** is stony.
- The **kind of fruit** is a drupe.

6. **Conclusion**:
- The correct option regarding coconut is that it is a drupe, the mesocarp is fibrous, the edible part is the endosperm, and the endocarp is stony.
