Answer

To determine the type of fruit that Cocos nucifera (coconut) is, we can analyze the characteristics of different fruit types mentioned in the question.

### Step-by-Step Solution:

1. **Identify the Fruit Types**: The question provides four options: Drupe, Cypsela, Berry, and Cremocarp. We need to understand the characteristics of each type.

2. **Understand Drupe**: A drupe is a fleshy fruit with three layers:
- **Epicarp**: The outermost layer.
- **Mesocarp**: The fleshy middle layer.
- **Endocarp**: The hard inner layer that surrounds the seed.
- Example: Mango is a common example of a drupe.

3. **Understand Cypsela**: A cypsela is a dry fruit that develops from a single ovary and usually has a hard outer covering. It is typically associated with plants like dandelions.
- Example: Dandelion.

4. **Understand Berry**: A berry is a fleshy fruit with three layers (epicarp, mesocarp, and endocarp), but all layers are fleshy.
- Example: Tomato is a common example of a berry.

5. **Understand Cremocarp**: A cremocarp is a type of fruit that has a bilocular ovary, meaning it can have two locules (chambers) and is often associated with plants like coriander and fennel.
- Example: Coriander.

6. **Analyze Cocos nucifera**: Now, we need to analyze Cocos nucifera. It has:
- An outer layer (exocarp).
- A fleshy middle layer (mesocarp).
- A hard inner layer (endocarp) that surrounds the seed.
- This structure matches the definition of a drupe.

7. **Conclusion**: Based on the characteristics analyzed, Cocos nucifera is classified as a drupe.

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