The fibrous __________of coconut yields coir.

Options

A. Endocarp
B. Epicarp
C. Endosperm
D. Mesocarp

Answer

To answer the question "The fibrous __________ of coconut yields coir," we need to identify the correct part of the coconut that produces coir. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Coir**: Coir is a natural fiber that is extracted from the coconut fruit. It is important to know what coir is and where it comes from.

2. **Identifying Coconut Layers**: The coconut has three distinct layers:
- **Exocarp**: The outermost layer.
- **Mesocarp**: The fleshy middle layer.
- **Endocarp**: The hard woody layer that surrounds the seed.

3. **Determining the Source of Coir**: Coir is specifically obtained from the mesocarp of the coconut. The mesocarp is the layer that contains the fibrous material used to produce coir.

4. **Eliminating Incorrect Options**:
- The **exocarp** is the outer layer and does not yield coir.
- The **endocarp** surrounds and protects the seed and is not fibrous.
- The **endosperm** is the part of the seed that provides nutrition, not a fibrous layer.

5. **Conclusion**: Since the mesocarp is the layer that yields coir, the correct answer to fill in the blank is "mesocarp."

### Final Answer:
The fibrous **mesocarp** of coconut yields coir.
