A tissue which makes up the husk of coconut and whose cells are dead, elongated and lignified is

Options

A. chlorenchyma
B. collenchyma
C. parenchyma
D. sclerenchyma

Explanation

To answer the question about the tissue that makes up the husk of coconut, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the Tissue in Question**: The question asks for a specific type of tissue that forms the husk of a coconut.

2. **Characteristics of the Tissue**: The tissue must have the following characteristics:
- The cells are dead.
- The cells are elongated.
- The cells are lignified (contain lignin).

3. **Understanding Plant Tissues**:
- **Chlorenchyma**: This tissue contains chlorophyll and is involved in photosynthesis. It is not lignified and is soft in nature.
- **Parenchyma**: This tissue is also involved in photosynthesis and is soft, with no lignin, thus not fitting the description.
- **Sclerenchyma**: This is the tissue that consists of dead cells, is elongated, and contains lignin, making it hard and stiff.

4. **Conclusion**: Based on the characteristics and the types of tissues discussed, the tissue that makes up the husk of the coconut is **sclerenchyma**.

### Final Answer:
The tissue which makes up the husk of coconut and whose cells are dead, elongated, and lignified is **sclerenchyma**.
